Below are links to our pages of optional addons you can use with our 14in1 systems, everything from our Head Guard which adds a low coolant sensor & alarm, to Head Guard Ultra, which adds low coolant & waterpressure sensors & alarms, to our range of wideband kits which will enable air fuel ratios to display, and weeven have a thermo fan triggering kit with relay. Any questions about the addons please reach out to our techteam and they will be happy to assist. Note EGT sensors are added from the Multi Gauge Base Packv2.6 page directly, take note of the options box near the add to cart button.

With our Head Guard and Head Guard Ultra add-ons, the JRP 14in1 gauge can be expanded to include a Low Coolant sensor and audible alarm. The Ultra add-on also introduces real-time Water Pressure monitoring, providing a comprehensive upgrade to your engine protection strategy.

Standalone low coolant alarm systems can cost upwards of $200 by comparison, integrating this feature into the JRP 14in1 system delivers significant value without the need for separate units or cluttered installs. The Ultra pack's additional Water Pressure input further enhances early warning capabilities by detecting abnormalities in cooling system pressure that often precede overheating or mechanical failure.

Whether it’s a gradual head gasket leak, stuck thermostat, faulty radiator cap, or a catastrophic loss of coolant Head Guard is engineered to alert you early, before it becomes engine-threatening.

Our Thermo Fan control addon is designed specifically for customers who want to control relays based on live temperature data from the gauge.

With this module installed, the gauge can act as a fully functional thermo fan controller, using sensor inputs like Water Temp to automatically switch fans on or off. The system supports user-definable temperature thresholds directly within the gauge, offering full flexibility without the need for an external controller.

Applications range from basic setups such as activating aftermarket radiator thermo fans to more advanced configurations like triggering fans for external transmission or engine oil coolers. It can even be used for custom solutions like activating intercooler water spray systems based on real-time Intake Air Temperature (IAT) readings.

For those serious about tuning and protecting their diesel engines, JRP is one of the only multi-gauge systems on the market that supports Diesel Air-Fuel Ratios thanks to our Spartan 3D wideband controller and O2 sensor.

This powerful add-on lets your 14in1 gauge display both AFR (10–40) and Lambda (0.69–2.76) directly on screen, giving you real-time insight into your engine's combustion health. You’ll find the Spartan 3D Diesel Wideband Kit in the add-ons section for our multi-gauge range.

But we don’t stop there. Once connected, you can activate a Diesel Rich Warning an exclusive JRP feature that monitors AFR levels and alerts you the moment they dip into potentially damaging rich territory. As far as we know, we’re the only standalone multi-gauge system in the world with this level of diesel protection built-in.

Two EGT Sensor Options

At JRP, we’ve always focused on delivering value for the Diesel 4x4 community. Back in 2018, we launched our v2 multi-gauge kits with a custom-designed EGT sensor known today as the JRP EGT v2. This robust sensor has served thousands of customers well, especially in turbo diesel setups.

As our customer base grew, we saw an opportunity to take things further. Rather than replacing the v2 entirely and increasing the base cost of our kits, we introduced the JRP EGT v3 as an optional upgrade. Both sensors are solid choices you simply choose what suits your setup and budget best when adding your kit to cart.

You’ll also find comparison photos to help you see the physical differences. For turbo diesel engines, EGT monitoring is a must and we’ve got two great options ready.

V2 EGT - Pyro Sensor

Our original JRP EGT v2 sensor is still a high-quality, proven option for most diesel applications. Built from durable 3030 stainless steel, the 3mm probe is shielded to prevent false readings from external grounding. It uses multi-core wiring (not single core like many cheaper alternatives), improving vibration resistance and long-term reliability.

Features include a Deutsch plug for easy installation and full heat shielding on the wiring. If you don’t have a history of EGT sensor failures or aren’t pushing high temps along with a lot of offroad use and vibration, this sensor offers excellent value and performance.

V3 EGT - Pyro Sensor

For customers demanding the best, the v3 sensor steps things up. We developed it using real-world feedback from workshops, dyno testing, and years of data. It builds on the strengths of the v2, with upgrades in materials, construction, and response speed.

The v3 uses a thicker 4mm probe made from high-grade 2520 stainless steel, offering improved durability, especially for pre-turbo installs or high-temp environments. Like the v2, it features multi-core wire and precision shielding to ensure accurate readings, but with higher-spec wiring and refined internal crimping. The tapered tip design improves response time, and testers have reported noticeably quicker reaction to rapid EGT changes under load.

If you're running a hard-driven diesel, the v3 sensor is the ideal choice. And since the upgrade cost is minimal, it’s worth considering for anyone who wants the most durable, responsive sensor we offer.

High Quality Sensors

The sensors included with our multi-gauge systems deliver high-end performance without the high-end price tag. We’ve tested them side-by-side with big-name brand gauges using reference-grade tools, and every sensor falls well within a 1% accuracy range.

We know how critical sensor accuracy and durability are they’re the heart of any quality gauge system. But in real-world use, chasing anything beyond 1% accuracy often means paying significantly more for a difference you’ll never notice. For 99% of users, that extra 0.1% just isn’t worth the cost.

With JRP, you’re getting reliable, accurate sensors built for performance without the inflated price.

Transmission Temp Sensor & Readout

If you're not planning to use Oil Temp, you can easily repurpose that sensor to monitor Transmission Temp instead no need to buy anything extra. Just change a setting on the 14in1 screen, and the gauge will display Trans Temp using the standard Oil Temp sensor supplied in the kit.

Want to run Water Temp + Oil Temp + Trans Temp all at once? That’s possible too but it comes with a small trade-off. Our kits also include an IAT (Intake Air Temp) sensor as standard, and we've designed its input port to be multi-purpose. You can plug either the IAT or a dedicated Transmission Temp sensor into that port.

So, if you want the full trio Water, Oil, and Trans Temp you’ll need to purchase our add-on Trans Temp sensor and forgo using the IAT sensor. We’ve maxed out the available input ports on the control unit, but this setup still gives you flexibility without needing a whole new system.

Dual Volts Inputs

One of the standout features added to our v2 control units is a second dedicated volts input—perfect for 4x4 owners running dual battery setups.

Now, you can monitor both your primary and secondary (auxiliary) battery voltages directly on the gauge. This has been a highly requested feature from the off-road community, and we're stoked to have it fully integrated. The secondary input supports a wide range from 8V to 36V, giving you flexibility no matter your setup.

This feature isn’t just for 4x4s, either. Performance vehicle owners may also find dual voltage monitoring useful for logging or managing separate power circuits—check out our 14in1 screen product page for more on how it can benefit your build.

OLED Screen

Our 14in1 Multi Gauge systems use a high-quality OLED screen rather than a traditional LCD, and the difference is noticeable from the moment you power it on.

OLED screens are brighter, clearer, and offer superior off-angle viewing, giving you far more flexibility in mounting the display. No matter where you place it dash-mounted, pillar-mounted, or tucked away you’ll be able to read your data easily and clearly.

One of the most important features of any gauge is readability in all conditions, and this is where OLED technology really shines (pun intended). Unlike LCDs, which can suffer from poor viewing angles and weaker backlighting, our OLED screens maintain strong visibility even when viewed from the side.

To ensure the screen is comfortable to read day or night, the 14in1 gauge also features:

• 3-Stage Automatic Brightness Adjustment – A built-in light sensor automatically dims or brightens the display based on ambient lighting.
• 5-Stage Manual Brightness Control – If you prefer, you can manually fine-tune the screen’s brightness to your liking.

Clear, vibrant, and built for real-world driving our OLED screens make sure your vital information is always easy to see.

Customisable Displays

The JRP 14in1 OLED gauge has four selectable screens that you can switch between with each having a different layout of the sensors and readouts displaying on each selectable screen, two of these four screens are completely customizable, as in which sensors or readouts you want displayed on the screen and where, the size & style of the readouts as well. You can see from the screen cell breakdown charts below the different options for sizing & styling of the readouts, along with which sensors are supported by the different size & style options.

Another feature of these 14in1 gauges multi is the ability to configure KPH, MPH, PSI, KPA, Celsius, and Fahrenheit independently. So it’s possible to setup the system so it uses KPH, Celsius & PSI for pressure readings. A lot of us Australian’s like our pressure readings in PSI and not KPA, so this can be done without a problem, no need to try and learn KPA if you are used to PSI.

Cell Size A – Standard

When the cell is set to size A, you can switch between the below readouts on that cell.

Cell Size B – Extended

When the cell is set to size B, you can switch between the below readouts on that cell.

Cell Size C - Chart

When the cell is set to size C, you can switch between the below readouts on that cell.

Sensors Have 1/8 PT Threads

At JRP, we're always looking for ways to make sensor installation more flexible and user-friendly. That's why we've adopted 1/8 PT threads for most of our sensors a thoughtful innovation designed to simplify your setup.​

Understanding Thread Standards:

Traditionally, sensor threads come in two main standards:​

• NPT (National Pipe Thread): Commonly used in North America.​
• BSP (British Standard Pipe): Widely used internationally, including in Australia and New Zealand.​

These differing standards often necessitate adapters, complicating installations.​

The Advantage of PT Threads:

Enter PT (JIS Tapered Pipe) threads, which are identical and interchangeable with BSPT (British Standard Pipe Taper) threads. This compatibility allows our sensors to fit seamlessly into both NPT and BSPT ports, reducing the need for additional adapters and streamlining the installation process.​

Practical Benefits:

• Direct Fit: Easily install our sensors into existing ports without sourcing extra adapters.​
• Time-Saving: Simplified installations mean you can get your vehicle back on the road faster.​
• Cost-Effective: Eliminates the expense of purchasing multiple adapters.​

Note: While our Water Temp, Oil Temp, Trans Temp, and Pressure sensors now feature PT threads for maximum compatibility, please be aware that our EGT sensors remain 1/8 NPT, and IAT sensors are 3/8 NPT. Any future changes to these specifications will be promptly updated.​

By integrating PT threads into our sensor designs, JRP continues to prioritize your convenience, ensuring our products are not only high-quality but also adaptable to your specific needs.

Optional Install Accessories & Sensors

To help you get the cleanest and most efficient install possible, we offer a growing range of accessories that pair perfectly with our multi-gauge kits. Whether you're chasing a neat engine bay or just want to make install day easier, these extras have you covered.

✔️ 3-Port Radiator Hose Sensor Adapters

If you're using our Head Guard or Head Guard Ultra packs, these adapters are a game changer. They allow you to install Water Temp, Low Coolant, and Water Pressure sensors into a single point—making what used to be a messy multi-sensor job simple and tidy.

✔️ Oil Filter Sandwich Plates

Our high-quality stainless steel sandwich plates (no cheap alloy here) fit between your oil filter and engine block, providing three 1/8 NPT ports for sensors like Oil Temp and Oil Pressure. They’re a great alternative to removing factory sensors or welding bungs into your sump.

✔️ Single-Port Water Temp Adapters

For simpler setups, we also offer single-port radiator hose adapters—perfect if you’re only fitting a Water Temp sensor and don’t need the full Head Guard setup.

✔️ Sensor Extension Cables – Coming Soon

While our sensors ship with generous cable lengths, we’re releasing 2m and 3m extension cables for customers installing into custom or larger builds. These will cover the vast majority of our sensor range.

✔️ Weld-In Bungs + Specialty EGT Fittings

We stock a full range of weld-in bungs for EGT, IAT, and O2 sensors. Plus, for those running systems like Redback exhausts in Australia—which use ¼ NPT rather than the standard 1/8 NPT for EGT—we offer compatible ¼ NPT fittings to save you the hassle of re-welding new bungs.

✔️ Tacho Adapters for Diesel & Petrol

Getting a tacho signal on older Diesels (or some Petrols) can be tricky. That’s why we carry a range of tach adapters that generate a clean signal from sources like the alternator or injector pump—ideal for displaying RPMs on the 14in1 screen.

✔️ GPS Speed Sensor Kits

If you're dealing with an old mechanical speedo or missing a clean speed signal, our GPS speed sensor kits provide a reliable signal input for the 14in1 system. They're affordable, accurate, and super handy for custom builds or retrofits.
