I am going threw all each electrical harness and found that the dash harness has burned wires and need a bunch of work. Anyone out there have a good used dash harness from a 87 Chevy full size truck or 87 to 91 suburban or blazer? I think these are all the same when it comes to the dash harness. Any help would be great!

I was at the pick-a-part today looking for an instrument cluster and they had a Sub but the cluster was gone. As I recall the wiring was still there. Not sure how much work it would be to remove as I've never tried for a dash harness.

If its a 87 to 91 suburban then it will work. needs to be undamaged, no burned wires.

I would hit the wrecking years too but I have a bad right foot and cant walk or stand too long.

Should be 1987-1989 k5, suburban, r and v series. How much of a harness you need, just under the dash part?

I need the complete interior dash harness. Mine is burned real bad. Just need to make sure it will fit my 87 with TBI.

Looks like you have a 1989 Suburban with a 5.7L with TBI fuel injection.

If its a good uncut and undamaged harness its should be the correct one. I do need the complete interior dash harness with all the plugs intact but I do not need the interior AC harness it plugs into, you can leave that one there.

PM me your number so I can call you to go over this. I could use some other parts from this Suburban.. want to talk about that too. Thanks a bunch for your help!!

Here is a pic of one out of a 1987 Chevy Truck without AC. This is what I need.
