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.\u003c\/li\u003e\n\u003cli\u003eAll 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.\u003c\/li\u003e\n\u003cli\u003eAEM 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.\u003c\/li\u003e\n\u003cli\u003eApex’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.

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.\u003c\/li\u003e\n\u003cli\u003eSpeedo \/ Tach Signal Conditioning\u003c\/li\u003e\n\u003cli\u003eThe 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 \u0026amp; 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.\u003c\/li\u003e\n\u003cli\u003ePlug-n-Play vs Universal\u003c\/li\u003e\n\u003cli\u003ePlug-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.\u003c\/li\u003e\n\u003cli\u003eRight Hand Drive (RHD) Conversions\u003c\/li\u003e\n\u003cli\u003eIf 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.\u003c\/li\u003e\n\u003cli\u003eDon't See It?\u003c\/li\u003e\n\u003cli\u003eIf you have injectors, throttle body, coilpacks or any other item that you do not see on the Options offerings, please contact us.

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.\u003c\/li\u003e\n\u003cli\u003eLS2\/LQ9 GM V8 Coil Pack Conversions\u003c\/li\u003e\n\u003cli\u003eWe 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\u003c\/li\u003e\n\u003cli\u003eplease contact us for details. NOTE: OEM Toyota JZ ECUs require an IGF signal produced by the ignitor chip. When the chip is removed for LS2\/LQ9 coil upgrade, an aftermarket ECU or IGF simulator box is required (not included with our harness), and the coils will be fired sequentially.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wiring Specialties","offers":[{"title":"Default Title","offer_id":48086529310872,"sku":"8Q8ZK","price":749.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0564\/0867\/0360\/files\/made-in-usa__69835.1730479441.jpg?v=1769754373","url":"https:\/\/frsport.com\/products\/universal-s14-ka24de-wiring-harness","provider":"FR SPORT","version":"1.0","type":"link"}
