I have heard of O.C.D. before.
It was a quote I heard from someone. I don't know who said it, but I always chuckle when people say someone is O.C.D. and all that person did was just do a neat and tidy job, especially when it comes to wiring. Being neat and tidy makes your life a whole lot simpler down the road if you ever had to take things apart again. I admire a person who does a clean install job. Having worked on running new wiring on others cars, I'd make sure the job was done properly, even labelling aftermarket wiring jobs for any future technicians so they could easily identify what it was for and not waste time tracing wires.
