Installing 88 Engine in 83 944. Solving Wiring Issues.




Mating the harness of an early (1983) car and late (1988) engine and ECU is pretty straightforward. The biggest challenge being connecting the new engine harness to the old chassis harness because they have different connectors. The early car has a 9-pin square shaped connector, the later car has a rectangular 14 pin connector.
Luckily, 90% of the wire colors and functions are the same.
Before hooking up the wiring, it is beneficial to take the old 9-pin connector from the engine harness and use that as a base so that in the future you can easily disconnect the harness. So, what happens next is you permanently splice the pigtails from the old harness' connector onto the clipped wires from the new harness.
As your splicing them It is pretty much straight forward Pin to Pin ie Pin #1 to pin #1. all the way to 9/9.
Pin #10 (blue/green) wire on the new harness. This is for the water temperature dummy light, a feature non-existent on the early chassis. So, just cap this wire, and pin # 13 red/green, is used for the air conditioner.
There are now two plain black wires on the old chassis harness that we need to take care of. These emerge from the #2 and #4 positions on the connector.
The number 4 black wire goes to the tach. So, a jumper wire needs to go from this wire to the black/yellow + black two wire connector that is part of the new engine harness. It is a lone split from the main engine harness and it is pretty obvious from its position that it is a dash wire.
The lone remaining black wire off the old #2 connector is for the O2 sensor warmer. On a race car this is not needed. So, this wire can be capped. Or, as it is hot with ignition, used to power additional gauges, which is what I did. I used this to power the low oil pressure light and oil temperature gauge.
That's it!
