Spoke to a harness manufacturer last week at the Portland Swap Meet and asked why I could not buy a basic wiring harness that would replicate my original wiring. Everyone I have seen has the GM column, power windows, radio and so forth as part of the kit. He agreed and has been asking his company why they won't build one and has never had an answer. This has been a problem for me for 15 years and that is why I elected to build my own. These trucks are very simple and the schematic in the shop manual lays it all out. My truck is 12 volt and I merely used the wire gauge specified on the schematic. good wire, good terminals and a good crimper is all it takes. My biggest problem is accessing the wires under the dash and its a problem I still would have with a kit.
