Need help with converting instr panel w/out gauges - The 1947 - Present Chevrolet & GMC Truck Message Board Network

kingnothin_36 · 05-08-2009, 10:27 PM

I have a 1972 chevy pickup and I am trying go from an instrument panel w/out gauges to one with gauges. But there is an issue, I noticed that my connection to the printed circuit is only 11 pins and the panel with the gauges have a 12 pin circuit. Also the two circuits run differently to different parts of the instruments. Is there a conversion I need to get to make it a 12 pin or what? Please help with any suggestions? Thanks!

You will probably have to get an underdash wiring harness -most of the suppliers have them.

Look in the parts section - there are used wiring harnesses for sale as well, but unless you're good with troubleshooting, I would buy a new one.

under dash harness is different, and so is the engine harness up front.

Kingnothin: You need one donor pin from another harness. I am doing this same thing now and figured that out also. I had a junk underdash harness that I just salvaged an extra pin from the dash plug. I can send you one if youd like, but you may find one closer-LMK
I am assuming that you are using GMC pauls how to on this (Rearrange wires from a idiot light harness to an instrument dash harness)- The link is on the FAQ page on this forum. If you need help, post here and I can assist

I currently don't have a donor that I would be able to pull from. If you could send me one that would be awesome. I will pm you with some info. I just found that link from GMC pauls, it looks pretty easy now if I only have to move a few wire around. Thanks for you help. Cory
