Hey everyone. I have an 85 Omni GLH. I'm looking for a diagram that shows the identification of the wires that plug into the back of the instrument cluster. (round one and a flat one.) I also need one for a 88 Daytona Shelby Z(round red and round gray.) Omni is carburated HO and the Shelby is turbo. In the middle of a swap. Please help!!!! Thanks!!!
