I just bought an 87 reg. cab shortbed 4wd on 40 boggers. It didnt come with an engine and the one that was in it was carbuerated. So when I put the TBI 350 from the 92 in there the wiring harness on the 87 doesnt match up mostly b/c its cut up. I can get the wiring harness from the 92 but how do I convert it to the 87 ecu? What else do i need to do to get it running? Is there any easier way?
