I'm planning on fabbing up my own gauge cluster for my 91 camaro. I ordered a used cluster from hawks third gen that i'm going to hack apart. It will be like the one someone else is working on who also posted here. I'm sure i could set up some gauges to fit just right using the stock cluster. What i need is a diagram showing which wires feed which gauges from the connection port behind the cluster. I'd like to hook everything up from that spot. Can i do it that way or am i overlooking something? I'd hate to spend 800 dollars on gauges and not be able to wire it up without major hacking and routing. Also, the fuel gauge is a 0-90 ohm right? Electronic speedo should work like the stock one without having to use any special sending unit. I think.
