While working on my car today, 1969 Mercury Cougar XR7, I have notice an issue with the wiring. Was it common practice to wrap a harness within a harness? I have power windows in this car and the harness for the window safety relay (2wires) is wrapped by itself and then is part of the speed control wiring and wrapped within that wiring. I don't know if it has always been like this or if these should be separate wire assemblies.
This is NOT a concourse restoration I'm doing, just wondering.
