We start by removing any excess wiring and plugs from your engine wiring harness to give it a cleaner look and eliminate unneeded systems. Any plugs that would have plugged into the donor vehicle are then removed as well. Any wiring you will need to connect the engine into your host vehicle is then run out cleanly and left accessable for you. All of the wires needed to run the engine will be clearly labeled for you to connect.

At this point we install new relays and relay sockets for the "FUEL PUMP" and "COOLING FAN". Engine harnesses from vehicles which had a "MAIN" relay will be equipped with a new "MAIN" relay and socket also. A new standard (OBD II ) diagnostic link will also be wired into your harness at this time, saving you the hassle of installing one after-the-fact in the vehicle.

The ECU will require inputs from minor sensors and systems that your project vehicle may not have. If left disconnected, the ECU will generate service codes and the engine may not run properly.
Enginewiring.com uses advanced, proprietary methods to eliminate these unnecessary inputs, ensuring that
YOUR ENGINE RUNS AT IT'S FULL POTENTIAL!
The affected areas of your harness will then be finished with new split loom tubing, so your custom car will have a clean, factory appearance.
