    Had a small electrical fire Friday. Anybody have a wiring diagram for an 89 Blazer? NOTE: Previous owners installed an 87 TBI 350 awhile ago. Make a difference?

    What section of the wiring had problems? I've got a good set of diagrams for the ECM harness on my site... just click the link in my sig, and go to the "ECM Pinouts 87-91 TBI ECM" link! /forums/images/graemlins/thumb.gif

    mechanical speedo or not? if it's still a mech speedo, then you should have no problem putting in a wiring harness, as long as you get one from a 87-89 truck. after that, they went to a different version of VSS and it totally sucks.
