I feel there are some communication issues, I'll try straightening them out.
In my first post, installing the harness I meant plugging everything in. The only swapped thing on my friends -95 is the -96 engine. Not gearbox, harness or ecu.
Can you explain why the trans need the ground, so I can understand how the car works better?
Yes I know this. I have experience with 850 but never done any engine swap.
My friend purchased a unknown engine, and yes we basically only installed the -96 engine to the -95. It has the -95 gearbox because the speed sensor is different to the -96 and we played the safe card there.misha wrote: ↑31 Mar 2022, 16:15So....you bought a non running engine from a project car and it also will not run in your car
Basically...you should just install the engine from '96 and keep the original harness and ecu from '95.
If you did that....check the cam sensor orientation which abscate mentioned...scrub the paint on transmission where main ground from the battery needs to bolt on and you should be good to go.
The issue is it might have paint between the engine block and transmission and thats why it gets bad ground.
I just feel like it doesnt matter if the engine is bad or not, the fuel and spark shouldnt be affected by a (for example) low compression engine?
