I'm surprised that whoever you bought the harness from didn't wrap the wires like they were originally. I just purchased a complete harness from Rhode Island Wiring for my 51 and they were all wrapped like the original. I can't say about your 41, but by the AD era the main harness from the firewall was wrapped in what basically amounted to vinyl electrical tape. Other areas, such as the fuel tank sending unit wiring and headlight and taillight harnesses were wrapped in the cloth wiring loom.
