If the vehicle is built for racing, and upgrading to an HP or Dominator ecu is a foreseeable possibility, select the HP \/ Dominator option. This specs your harness to be terminated with the standard Holley eight-pin wideband o2 sensor connector. A wideband adapter (Holley part no. 558-463) will be required, but when switching to an HP or Dominator ecu, the adapter can be discarded, and the proper sensor for these ecu's can be connected directly to the harness.\u003c\/p\u003e\n\u003cp\u003eIf the vehicle is more of a street-driven \/ daily driver, and it is not ever anticipated to run this harness with an HP or Dominator ecu, you can opt to have the harness terminated directly with the six-pin connector for the Bosch LSU4.9 sensor. This eliminates the need for the adapter, which can make for a cleaner installation, with one less potential failure point in the system. Should plans change, the harness can still be modified for use with the appropriate o2 sensor for HP and Dominator ecu's, but will require cutting and re-crimping.\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. They do however still require external drivers.

The long lead length is approximately 6in longer than a standard Holley harness, and is plenty of length for comfortably mounting the ecu under the passenger seat of most vehicles. The short length is 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.

While possible, Holley efi is not properly equipped to control factory VCT in normal applications for most users. All performance cams currently available for the Boss platform require locking out the camshafts, eliminating VCT. Lockout kits are available for use with both stock and aftermarket camshafts.\u003c\/p\u003e\n\u003ch2\u003eOrdering Information - Please Read!\u003c\/h2\u003e\n\u003ch3\u003eECU\u003c\/h3\u003e\n\u003cp\u003eThis harness is compatible with HP, Dominator, Terminator X and Terminator X Max ecu's.

If the vehicle is built for racing, and upgrading to an HP or Dominator ecu is a foreseeable possibility, select the HP \/ Dominator option. This specs your harness to be terminated with the standard Holley 8-pin wideband o2 sensor connector. A wideband adapter (comparable to Holley part no. 558-463) will be included to use the LSU4.9 sensor required with Terminator X ecu's. Then, should you switch to an HP or Dominator ecu down the road, the adapter can be discarded, and the proper sensor for these ecu's can be connected directly to the harness.\u003c\/p\u003e\n\u003cp\u003eIf the vehicle is more of a pro touring or street-driven \/ daily driver, and it is not ever anticipated to run this harness with an HP or Dominator ecu, you can opt to have the harness terminated directly with the 6-pin connector for the Bosch LSU4.9 sensor. This eliminates the need for the adapter, which can make for a cleaner installation, with one less potential failure point in the system. Should plans change, the harness can still be modified for use with the appropriate o2 sensor for HP and Dominator ecu's. It will require some cutting and re-crimping, but is a relatively low hassle for anyone with a basic experience and wire harness tooling.\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 Boss engine, 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 and tucks 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\u003eOne of the most unique features of the Boss engine is its hemi heads and two spark plugs per cylinder. The engine has just 8 coil packs, each firing its two plugs per cylinder simultaneously. These are a \"dumb\" coil, and require a pair of external drivers - Holley p\/n 554-122 (sold separately).\u003c\/p\u003e\n\u003cp\u003eGenerally speaking, if making over 900whp or 30psi of boost (which ever comes first), an IGN-1A \"smart\" coil is recommended. Our standard configuration for IGN-1A harnessing is for eight coils, mounted on the valve covers. This requires block-off plugs for the secondary set of spark plugs.\u003c\/p\u003e\n\u003cp\u003eHarnessing solutions for remote-mounted IGN-1A's, as well as 16 IGN-1A's coming soon.\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\u003eFor cable drive throttle bodies, we provide an adapter harness to extend out to the throttle body and idle control valve. If running drive-by-wire, the cable drive stub tucks out of sight and out of the way under the intake manifold.\u003c\/p\u003e\n\u003cp\u003eFor drive-by-wire throttle, a Terminator X Max or Dominator ecu is required. \u003c\/p\u003e\n\u003cp\u003eOur harness offering for factory DBW throttle includes a lead that is compatible with a Ford accelerator pedal.
