I recently purchaced an 85 k5 which was formerly a diesel. The previous owner swapped out the diesel for a 400 small block but left the wiring a mess. I discovered a wiring nightmare behind the instrument cluster when troubleshooting a short. It appears that the cluster was replaced with one from an earlier year, as it doesnt fit properly, the gauges havent worked right since I got it and hes got a homemad wiring job back there. Anyway, now Im attempting restore this mess and was wondering if anyone knew where I might get a wiring diagram of the instrument cluster and its harness. The harness that plugs into the cluster has about 18 wires to it which are numbered. I need to figure out what each of the wires goes to (1 -18). The hot wires are easy to determine, but the rest im clueless about. Does anyone know if a Chiltons or Haynes manual has a diagram detailing this harness / cluster or where I might find such a thing? Any help would be appreciated...
