Hi. I am in the final stages of the engine and transmission swap from a 1990 S2 into an 89-944 automatic.
Done: engine, transmission, pedals, radiator, front wiring harness etc.
Problem now is getting it to start. I did a lot of research and trials.
I discovered the ECU is bad. Got a used one.
Now I have power at the coil, igniter at the left front headlight, power at the 14 pin connector at brake booster. I get power at the 14pin connecter at the passenger foot well only when I jump the DME 30 87 and 87a. Still no start.
The 89 2.7 interior wiring harness does not have the receptacle for the 14 pin connecter at the passenger foot well. Research indicates that 14 pin connector only powers the tach and oil pressure light.
Here is the question: instead of pulling the HVAC to remove the front interior wiring loom, is there any way I can rewire the harness to make the tach work and turn off the oil light?
