Alrighty. Read the whole thread, have a couple questions
I pulled a DIC and harness (down to the side of the dash and cut it) from a '00 TrailBlazer edition S10 Blazer. It is the short style with all functions. My truck is a '96, running a '98 drivetrain, a frankenstein harness, and an '02 411 PCM. The headlight and engine harnesses are from the same '98 Suburban that had a comp/temp mirror, so I already have the temp sender in place. The dash harness is from a '00 2500 4WD (454), I'm not sure if it had a comp/temp mirror, but the harness was there (blue plug) to plug my mirror into. My taillight and fuel pump harnesses are still '96, but that will change in the next couple weeks when I change the fuel pump to accommodate the later harness (mainly so my fuel gauge and brake lights finally work!).
My questions are -
Though the harness was there, my mirror is not working. I have swapped in two others to be sure, and none of them do. Why would this be?
Once I figure out why they aren't working, could I use the existing wires from the mirror harness to run the DIC?
Thanks
