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. ECU Patch Harness - This optional item eliminates the need to cut into your engine harness for accessories.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.MAP sensor harness should be purchased with the PFC. The MAP sensor is wired separately, from the PFC box directly to the sensor. Apex’i PFC conversions ONLY include the IAT sensor in the main harness.ECU control of a Boost Control Solenoid is also available on most harnesses. Flex Fuel support is available if desired. 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.Controllers like an AEM UEGO Gauge Kit or the Haltech CAN wideband unit should be used. For ECUs that do not process a raw wideband signal, a controller must be used. 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.Select the Oval or Rectangular connector style in the options to match your WB O2 connector. The LSU 4.2 Version of the WB O2 Sensor SHOULD be used, as per AEM and ECU Masters. 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.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.
