working on a 87 cutlass supreme 4dr that was plauged with bad wiring that inevitably started a fire. after a couple dayss weve gotten almost evewryhting back to working order ( other than the smell ) and the ins cluster does not light up. i bypassed all the factory wiring and ran new wires for the parking lights, but im having trouble getting the ins cluster lights working on this system too. im five minutes from drilling new holes for afermarket bulbs but id rather just use the factory equipment here to avoid cutting up the dash more than weve had to already. does anyone have a wiring diagram for the three plugs on the back of the instrument cluster? i know the illum wire should be brown, but after the fire, all the wires are brown. any help here would be greatly apreciated.
