Description
It’s FINALLY here – fully functional interior in your 350z with an RB25DET NEO engine swap. The Wiring Specialties CANbus harness does the trick…Tach, engine temp and no fault lights for traction control and stability control. Have a properly running car again, with the power of an RB NEO engine. All of these features come with NO CORES needed. Our Pro-Series is ideal for those looking for the best aesthetics, weight savings and reliability. This harness completely replaces the 350z / G35 original engine harness with a PRO series RB25DET NEO harness with proper fitment. This Wiring Specialties PRO Series harness was designed from the ground-up, specifically for a USDM LHD Z33 350z (2003-2006) with an RB25DET NEO engine swap. The harness is designed ‘Tucked’ for a clean installation. The harnesses are built to exceed OEM spec for wire quality and power/ground routing. Wiring Specialties has developed the CANBUS converter device to allow full gauge functionality, fan control and all of this in a plug and play package. No CORE needed, Plug and Play, startup guaranteed. 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. ENGINE: RB25DET NEO Any RB25DET NEO from R34 1998-2002 Skyline GTS/GTST Any RB25DET NEO from WGNC34 Nissan Stagea CHASSIS: USDM LHD Z33 350z Any USDM LHD Z33 Nissan 350Z manufactured in 2003-2006 Retains factory FANS, Speedometer, tachometer, engine temperature gauge, oil pressure gauge, alternator charge light, reverse lights and wipers. The Wiring Specialties harness provides proper 350z gauge cluster functionality for the engine swap. ECU output functions such as Tach, Engine coolant temp, CEL, Speedometer, fuel gauge and illumination are all supported by the proprietary CANbus controller, included in this kit. Fans functionality – the factory Z has very capable fans and controllers. We suggest keeping them for the swap, when possible. The Wiring Specialties CANbus Controller retains the factory fan functionality, with pre-set engine temp turn ON and OFF points. We also provide an override for FULL ON fan function by engaging the DSC button. Sleek and clever! Plug and play features of this harness require the OEM 350Z body harness, body control module and fuse boxes to be UNMODIFIED. The harness utilizes a number of relays and controllers that OEM 350z, so they need to remain on the chassis fuse box, in stock form. For proper Oil Pressure Gauge function, the 350z / G35 OEM oil pressure sending unit needs to be used (located near the RB Oil filter). In most cases a relocation line needs to be used in order to use the Nissan sensor with the swap. Harness connection will be provided to reach the passenger side shock tower for sensor relocation (optional). Traction / Stability control is not functional with this swap.

Click HERE to download and submit the ECU / Build details form with your order, or we will contact you once the order is placed to collect the needed details. AEM Infinity, Link and ECU Masters products (and some other standalone ECUs) are able to process a wideband signal input wired DIRECTLY to the ECU. The LSU 4.2 Version of the WB O2 Sensor SHOULD be used, as per AEM and ECU Masters. Select the Oval or Rectangular connector style in the options to match your WB O2 connector. All ECUs that are unable to process a wideband signal directly, will be wired for a FACTORY O2 sensor and a labeled flying lead will be provided to connect the ECU to the Wideband controller. For ECUs that do not process a raw wideband signal, a controller must be used. Controllers like an AEM UEGO Gauge Kit or the Haltech CAN wideband unit should be used. AEM Infinity, Motec, Link and ECU Masters harnesses are pre-wired for Oil Pressure, Fuel pressure, Oil Temp, IAT and MAP sensor wiring directly to the ECU. Flex Fuel support is available if desired. ECU control of a Boost Control Solenoid is also available on most harnesses. Apex’i PFC conversions ONLY include the IAT sensor in the main harness. The MAP sensor is wired separately, from the PFC box directly to the sensor. MAP sensor harness should be purchased with the PFC. 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. ECU Patch Harness – This optional item eliminates the need to cut into your engine harness for accessories. Use the length of wire provided between the wiring harness plug and the ECU itself to install accessories such as air-fuel meters & controllers, electric boost controllers, rev/speed meters and more. 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.
