The Snakes Alive CMP Wiring Project

Jordan.

For most of the wartime production, that shielded harness was the type used for all Wireless Vehicles, all weight classes. Two identical harnesses were in production: the standard cloth loomed ones used on none wireless vehicles, and the metal shielded looms for wireless as you have shown.

At some point late in the war, I do not know when, the practice of producing two separate wiring harnesses stopped and only one was produced thereafter. This final version was essentially a shielded harness like you posted, but with an extra overlay added, the outer jacket is some sort of fibre/cloth impregnated with a black, tar like substance.

I have been told that once the final version arrived, it was to be used as replacement harness in all vehicles. Perhaps it was felt that all transport would benefit by better electrical shielding and from that point on, only Wireless Vehicles had the extra ignition shielding added. It has also been suggested the extra jacket over the loom was a corrosion prevention asset.

In any event, you are OK with the shiny shielded harness on a CMP Wireless Vehicle.
