90 engine wire harness AND ECU into a 91

[Bouche Dag]

If I were to put a 90 ECU and harness into a 91 motor, nothing would have to be changed (pins 6&14), correct?

Also, it is a simple plug and play mod, right?

You need a 90 ptu, cas, and coil.

You are correct in that you would not have to switch pins 6 and 14 but you will need certain parts from the 90 to put on the 91 motor or modify the wiring harness. A little searching will tell you what you need but I you will need to cam sensor coil pack, and ptu and a few other things

Edit: beat me to it

I'm embarrassed to say that I dont know what a ptu is. If its for an auto then I wouldn't need it. Car is a 5spd

Referred to my trusty chilton manual to figure out what the PTU is. Thanks guys.
