The long lead length is approximately 66in from the back of the intake manifold to the NEXUS A connector, and is plenty of length for comfortably mounting the ecu under the passenger seat. The short length is approximately 40in, intended for mounting the ecu on the dash bar of a caged car or in the glove box, without wadding up a bunch of excess length.\u003c\/p\u003e\n\u003ch3\u003eStarter\u003c\/h3\u003e\n\u003cp\u003eThis harness features a starter solenoid lead built-in, fully loomed and labeled. The starter solenoid is mounted directly to the starter motor on Godzilla engines. If swapping into an older Ford chassis that has a solenoid mounted on the fender or firewall, it is not needed and can be removed from the engine bay.\u003c\/p\u003e\n\u003ch3\u003eOil Pressure\u003c\/h3\u003e\n\u003cp\u003eThis harness is plug-and-play with a factory Ford oil pressure sensor.

Haltech generally recommends the NTK sensor only for heavy methanol applications.\u003c\/p\u003e\n\u003ch3\u003eInjector Style\u003c\/h3\u003e\n\u003cp\u003eThis harness features an injector harness stub, compatible with injector harnesses from Holley. Harness kit includes our Holley EFI-compatible injector harness specific for the Godzilla, based on your choice. If you already have an injector harness from Holley, it can be used with this engine harness, but our injector harness routes much nicer.\u003c\/p\u003e\n\u003ch3\u003eIgnition Coil Style\u003c\/h3\u003e\n\u003cp\u003eYour selection automatically adds the proper coil sub-harness kit to your cart, to make connections directly to all eight coils.\u003c\/p\u003e\n\u003cp\u003eFactory Godzilla coils have proven to be reliable for big horsepower, much more so than the factory Coyote and Modular coils. 20-22 model year coils are a \"dumb\" coil, and require external ignitor modules. Please call for further information and to order.\u003c\/p\u003e\n\u003ch3\u003eThrottle Body\u003c\/h3\u003e\n\u003cp\u003eThis harness is highly adaptable and compatible with both cable drive and electronic drive-by-wire throttle bodies, without leaving unused connectors dangling in the engine bay.\u003c\/p\u003e\n\u003cp\u003eWe provide an adapter harness to extend out to the throttle body and idle control valve (if applicable).

With the solenoid unplugged, or effectively eliminated, oil pump bypasses to full flow, which can result in excess of 140psi. If running a factory oil pump and pan, the factory solenoid must be utilized to regulate oil pressure.\u003c\/p\u003e\n\u003cp\u003eIf solenoid is elminated by running an aftermarket pan, or modifying the factory pan, oil pressure must be regulated mechanically.

For this reason, we designed the harness with an external power lead, where injector power, coil power, ecu power, starter solenoid power, fuel pump output and more are terminated with a Deutsch connector for easy hookup in a centralized location to your choice of relay center, or even a PDM like the RacePak SmartWire or ecuMaster PMU.\u003c\/p\u003e\n\u003cp\u003eFor a true standalone installation, we offer a basic yet inclusive relay block that includes:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e40A relay for aux \/ fans (3x)\u003c\/li\u003e\n\u003cli\u003e40A relay for fuel pump\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eStarter lead, to connect to starter \/ neutral safety switch\u003c\/li\u003e\n\u003cli\u003eIgnition switch lead from both pins A13 and A26, to connect to ignition switch.\u003c\/li\u003e\n\u003cli\u003e10ft unterminated flying lead wires for fuel pump, fan and switch activators.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Jolt Systems","offers":[{"title":"Short (40\") ecu Behind Dash","offer_id":47698126373108,"sku":"10-019","price":850.95,"currency_code":"USD","in_stock":true},{"title":"Long (66\") ecu Under Seat","offer_id":47698126405876,"sku":"10-018","price":870.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2307\/3489\/files\/10-018_Godzilla_-_HT_NEXUS_02.jpg?v=1771513537","url":"https:\/\/joltsystems.net\/products\/ford-godzilla-engine-harness-system-haltech-nexus","provider":"Jolt Systems","version":"1.0","type":"link"}
