I need the Pin Out for the ecu in a 89 XR7
Can anyone provide it?
I am doing a transplant from a wrecked 89 XR7 to a 91 mustang fastback.
Also if anyone happens to have it the Pin out for the 91 Mustang 2.3l ECU.

If you are going to do this you need these,

The ultimate book to have is the PCED or Powertrain Control Emissions Diagnostic Manual, but I did not see any listed. Definetly buy the EVTM and Shop manual though...Dont bother with the aftermarket manuals.

I have the Shop manual for the xr7 and have one for the 91 mustang on the way. I didn't see a actual pin out for the ecu in it, unless I missed it. would the electrical manual have it?

Yes it will. Thats why the PCED manual is so much better. I knew the shop manual would be of no help electrically. But its still good for you to have. You can figure anything out with the EVTM as long as you know how to read it. Its just a little more spread out in the manual than the PCED
