How do I make my 89's check engine light work with LS swap?
Sorry if this is the wrong section for this question, but I figure it is swap related.
I just picked up a clean 89 Scottsdale that has a 00' LS engine swapped in. It is using a stock 4.8 and ECU, and what I am told is a Painless harness.
I have 2 leads from the harness that are for a check engine light. The info I need is on the truck side.
The light is currently on all the time as the stock ECU is gone. I just want a heads up on where to tap into the dash harness to make it work with my new ECU.
Thanks in advance!
