87 R10 truck dash harness needed!

circuitguy · Sep 21, 2014

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.

90 and 91 had electronic speedos, iirc.

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.

still need the harness?

circuitguy · Oct 24, 2014

Yes, still need one.

cobra20 · Oct 25, 2014

well I'm hitting a pick an pull on Sunday I'll see what I can find

circuitguy · Oct 26, 2014

Cool!! Let me know what you find.

cobra20 · Oct 26, 2014

ok I got most of it apart. I need to go back later this week and finish pulling it out, do you need it where the wires attach to the ac system? Also here is the vin of the truck it is coming out of 1gngv26k6kf139366

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.

I have a complete one out of a 1991 R-2500 Suburban if anyone has a need

I think 91 has an electric speedo, wont work for my 87.
