Because we are not auto-electricians, it is important to follow specific procedures in disconnecting lighting. If not done properly, there can be shorts, blown fuses and even possibly damage to electrical parts. It also could mean a lot of wasted time when dealing with problems later let alone having to “please explain” to customers. Any issues that occur (and I have heard of a few nasty ones with tricky luxury vehicles) is time not removing dents on another customer’s vehicle.

Listed below are possible general procedures and typical types of wiring to consider. As suggested they are general procedures and there are vehicles you will find that are different. Experience with dealing with the various makes and models will help.

Note that these procedures related to the removal and replacement of parts process and should be considered together.
