Once I got this far, I realized that if I want to use the 92 style heater control. I'm going to have to replace my heaterbox, the reason being. The 92 style control is a vacuum style, my old 84 is cable driven. So I got a 92 heater box, and it bolted right up. Now just have to connect the vacuums lines to where they need to go.You may have noticed I took the carpet out. I decided that since I was this far, I might as well do a full interior restoration. So going to replace the carpet and all the plastics, door panels, seats, everything inside.I'm really tired of the blue interior, so going to go with a dark charcoal I think. Also going to try and find some leather seats out of a 4th gen Camaro. They just look nicer and more comfortable plus they bolt right up.So now that I have the heaterbox installed, I was ready to attempt to install the 92 dash. Overall, this wasn't too difficult. The most difficult part was finding wiring diagrams for both the 84 and the 92. But once I was able to obtain these, I was good to go.Hooking up the dash was pretty straight forward. There is a main harness that comes in through the firewall labeled as C-100. Physically this harness did not change from 84-92. The only difference is the pins/wires may be in different locations. Well all I had to do is, move the pins/wires on the 92 dash, to match where they were on the 84. Then once I did this, I just connected the harness to the harness on the other side of the firewall. Bingo, almost everything worked!! I did have to ground a pin on the cluster. The 84 must not have used a ground here, or something. But once I did that, the entire cluster worked.So here is where I'm at right now with the 92 dash install. Everything on the Cluster appears to be working. Here is the new Cluster and dash installed.
