also if right message board can a 87 305 ecm for tpi work on a 92 going to tpi???
if not no big loss gotta for a good deal on this sight
placew iz better then facebook

 

First off, leave your dash harness alone. Modifying that will only open up a HUGE mess

Easiest way to do a TPI swap for a 90-92 car is to use a 90-92 TPI harness. An 87 harness can be made to work if the connectors are repinned

 

thnxs for the advice is that too much of a pain to do? if not ill try saves me money

and ecm should still work correct?

 

They can be made to work by repinning the 87 harness to 90-92 standards

 

sry for repeat message thanks for info
