I had to trouble shoot the wiring on a street rod that was wired that way once gag1025. What a pain in the Keester. Worse than that was the fact that the guy who did it originally didn't follow through with the color coding of the wire all the way on a run. You might have a blue wire leaving a switch on a circuit and where he ran out of wire he changed to yellow or black. Nothing on the car was colorcoded as far as actually color codes go.

Then there is my best friend's roadster back in the late 70's that was 100% wired with red wire. Correct gauge of wire but every wire in the car was red because the builder had gotten a deal on a few large rolls of red wire. I had to figure out the tail lights laying on the ground in a parking lot one night. I had the flash light, test light and knowledge to use them.
