PRO Series Plug-n-Play for R32 GT-R AWD
Configured for the Haltech Elite 2500 Aftermarket ECU

This Wiring Specialties PRO Series harness was designed from the ground-up to exceed OEM specifications for wire quality, power/ground routing. With our optimized and 'tucked' approach the end result will be a clean and worry free installation with a guaranteed start up.

This harness is specifically engineered for a JDM RHD AWD Nissan Skyline R32 GT-R with the RB26DETT engine & AWD Transmission using the Haltech Elite 2500 Aftermarket ECU. It was developed in house on an actual RB26DETT engine to ensure a perfect fit to all engine connections.

Wiring Specialties offers a number of options for common performance upgrades for this product. Build your perfect harness by selecting from the available options to the right, and as always - if you have any questions, please reach out to us.

FAQ & OTHER DETAILS

• Alternator Charge Cable - This item ties the starter/battery directly to the Alternator output, which allows the improved power routing on our harness to eliminate the wire running from the alternator to the fusebox and/or battery while still charging the battery normally.
• Grounding Kit - Our Kit ties a number if engine components to the body of the car and ensures that you will not have issues resulting from poor grounds. The Grounding Kit utilizes Ultra High temp fiberglass sleeving to allow installation under or around exhaust components. Very flexible mounting options allow you to connect the block, head, battery tray, alternator case and chassis to completely eliminate all grounding issues.
• Speedo / Tach Signal Conditioning - The Dakota Digital SGI-5 unit for Speed and the SGI-8 unit for Tach can 'condition' the signal to compensate for cross-platform swaps and/or changes to the number of cylinders. If the Option exists to ADD either unit on the harness page for your swap, then you need them for proper speedo & tach operation. Please note that some transmissions (350z, BMW ZF and S15 Silvia for example) do not have a speed sensor and will require a non-harness based solution like a GPS speedo. Most Nissan to Nissan swaps can simply adjust the tachometer to compensate.
• Plug-n-Play vs Universal - Plug-n-Play harnesses connect to your car's underhood fuse box for power and to connectors under the dash for gauges etc. Universal harnesses do not need an underhood fusebox to connect to and the wiring for gauges and warning lights is provided as a 'flying lead' which are bare wires labeled with their function.
• Right Hand Drive (RHD) Conversions - If you used ALL the stock LHD chassis connectors for your RHD swap, order the LHD version of the harness. If you used ALL the clip/swap RHD chassis connectors, order the RHD version of the harness. If you used a combination of LHD and RHD chassis connectors, please contact us as our harnesses will need modification.
• Don't See It? - If you have injectors, throttle body, coilpacks or any other item that you do not see on the Options offerings, please contact us. Chances are we can do it!
• Battery Cables / Battery Relocation - The battery must be connected to the starter, so you need a battery cable from the positive battery terminal to the starter main power lug. Typically this positive battery cable also powers up the main under hood fusebox, which runs many of the non-engine items on your car like interior lights, dash power and headlights/taillights. Please make sure you have prepared for this as each install is different.
• LS2/LQ9 GM V8 Coil Pack Conversions - We offer an upgrade to the GM V8 LS2/LQ9 Smart Coils on most of our harnesses. This will eliminate the ignitor chip completely (when present), and allow you to use the high performance LS2/LQ9 Coil Packs which are easy to find. Install on JZ or RB engines keeps the coilpacks in their original location over the spark plug with the use of a mounting kit from MOJO Performance. The kits include brackets, mounting hardware, rubber boots and contact springs and can be added to your order by selecting them from the Options list to the right. Install on other engines will require a custom mounting solution and extra parts - please contact us for details.
