They still make the Packard 56 blade pins to re-pin the bulkhead connector. I have an 86 GMC that was 6.2 diesel originally, the previous owner blew it up and went with a 350. Needless to say the harness was totally butchered, so when I decided to drop in a new crate engine last fall I totally rebuilt the harness myself. It only cost me about $130 plus my time. I just took the old harness, peeled the tape off it and went wire by wire. Heads up the pink wire that went to your glow plugs, makes a damn fine HEI distributor power wire. other than that all the temp, oil, and alternator wires remain the same.
