Stand alone harness. This does not involve butchering/tie into original car harness. It is for engine only and adapts to any car but is specific to particular engine and its corresponding computer (ecm). It comes with a relay package and a fuse package. Relays are typically for ignition and fuel pump. Fuses in fuse block protect devices that the harness serves such as injectors, O2 sensors, etc. As a rule you put the relay/fuse block assembly inside of the car along with the ECM connectors which will be part of the standalone harness. Thus the ecm connectors, relays and fuses are typically inside of the vehicle and the remainder of the harness has dedicated places to go on the engine such as alternator, injectors, sensors, cooling fan relays, etc. Typically a always hot and or a switched hot is required to attach to the relays on your end.
It is customary for harness providers to ask you questions related to what type of alternator connector, drive by wire or cable driven throttle body, etc. They, in turn custom fabricate every harness to your particular engine and ecm. Hope that helps. Prices are generally 5 to 6 hundred dollars.
