I've just finished a 3litre 16V S2 transplant into an 86' 944. It will not run without a dme jumper! I know there was a wiring change from 87'. I have transplanted the entire S2 engine bay harness but there are differences between 86 wiring and later cars.

I have access to wiring diagrams ect but I'm completly ignorant about this stuff. Been here before, but my wiring mate is long gone so I'm up shit creek

if by jumper you mean DME relay you can bypass that i think it was 30 to 87b or some thing like that, if you have the Haynes manual it will tell you, i would have moved the entire electrical system. I have had issues with my 924s as none of the wires line up, because its a 944 harness on 924 dash electronics, you may need both schematics to trace and connect all wires correctly, the colors may not match.
