I am installing the dash and gauge cluster from a '91 Camaro into my '84 Camaro. I need schematics for the pin configuration of the two cluster plugs (c1 & c2) for both model years. They are different and in order for this to work I will need to re-wire both plugs. Each plug has 14 pins which are numbered. I checked with a buddy at a local Chevy dealership, & was told this information is only in the Helm's shop manual. I am praying that I can find a few Camaro enthusiasts, like myself, who would be kind enough to help me out. Any information you can provide would be greatly appreciated. Thanks!

 

Pinouts are shown in the Chilton's manual, if you have one.

 

I Did this to my 87 sport coupe I will see if I can find the diagram I made up while I was doing it. Couple of things you will need is electronic speed sensor that goes in the trans and a speed sensor buffer. The 91 dash is electronic and uses no cable.
