Makes you appreciate different colored wires. Had an issue on a Freightliner with the electric side mirror. Kept writing it up for repair. Eventually, the shop mechanic showed me the wiring diagram where every wire was white. I relented that I could live without the power mirror functioning.
OH i found this out when i started working on school buses, all wires are white with numbers stamped on them ,what a pain in the A#* its hard to read the numbers, and im only 50..
