If you are looking to clean up the ZF rear, I found a cheap, easy trick to cover that odd reverse switch hanging off the ZF. A 35mm film can is just about a perfect slip fit over that switch. Put a few wraps of black electrical tape around it if it is too loose. Buy a short length of the corrugated/split cable cover sold at the auto stores to cover the two wires, and drill an appropriate hole in the bottom side of the film can to accept the cable cover. You may have to rework the switch connectors, or switch to a smaller crip-on terminal. Voila! Simple, clean and subtle.
