1987 r30 350 wiring
bought this truck last month. The guy changed from TBI to carb because the TBI wiring was all melted and burned. He cut wires off at the fuse block. need help identifying the wires off the block that go to 1) oil pressure gauge & 2) temp gauge. I cannot figure out which wires go to the gauges from firewall side for those gauges. I know where both senors/switches are just need colors of wires that go to them.

Download the 87 & 88 wiring diagrams.
They are full line light truck diagrams so they have more than just the squarebody wiring. You'll need to page down to the RV schematics.
