General Motors HARNESS SYSTEMS

We have done a great deal of research on General Motors wiring harnesses in order to provide you with the most authentic wiring systems possible. While doing this research, we had the opportunity to study original harness blueprints and specifications for some General Motors products. All of the data we examined specified that the wire was to have a natural cotton base color (a light tan) braided over the rubber insulation, with tracer colors woven in for wire identification. The tracer colors would consist of a single thread parallel tracer or two single thread crossing tracers, as specified on the harness blueprints. After the cotton braid was applied to the wire it was to be given a protective coating consisting of a heat, oil and water resistant varnish. This protective coating would color with age and cause the original wire to appear dark yellow, orange, or brown. All the wire we use for General Motors vehicles conforms to the original color codes as specified by the manufacturer.
One note on our General Motors harness systems: At this time we cannot supply the original type GM twist connectors, the rear body plug, or the turn signal switch plug. We do provide substitute connectors used in that era and instructions for the salvage and reuse of your original plugs if you so desire. We have been unable to find a supplier whose connectors have the original appearance and quality to meet our standards.

You must reuse the junction boxes, conduit cap ferrules, light sockets and special connectors (special instructions are included).
Buick harnesses from 1930 to 1933 had the wires run through non-metallic asphalt loom. We provide these harnesses assembled with the wires through the loom and terminals installed. You must reuse the stamped metal loom junctions, loom clips, light sockets, and any special connectors.
