This purchase is for one harness conversion for use with YOUR PCM and YOUR ENGINE WIRING HARNESS.

Just to clarify, NO PCM or HARNESS is included only the MODIFICATION of your supplied PCM and engine harness.

Your PCM will receive our basic flash to be tuned to your needs:
Our standard power tune will ensure the engine runs code free, and will correct for wheel/tire size, rear gear ratio, cooling fan temperature (where applicable), rev limit, upper speed limit, removal of VATS anti-theft, and will dictate how soft or firm the transmission shifts.

We’ll remove 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 also removed as well.

Any wiring you will need to connect the engine into your host vehicle will be left accessible for you.  All of the wires needed to run the engine are clearly labelled for you to connect.

We install new relays and relay sockets for the “FUEL PUMP” and “COOLING FAN” (Where electric fan is used).

A new standard OBD-II diagnostic link is also installed with this harness conversion, saving you the hassle of installing one after-the-fact in the vehicle.
We can support or remove the 4L60E/4L80E Transmission from your PCM and harness at no additional cost if your application requires a different transmission.
