tailight housing/electrical removal?

[airborne3502]

what's the best way to remove the housing for the tailight & reverse/side marker lights without damaging the electrical?

I'd like to be able to disconnect the wiring without cutting it so that I can just pull everything ( the bulb/housing & wires ) right out of the tailight & reverse light holes once I uscrew the metal housing. Does the wiring disconnect like the bed did from the frame with a plug? It looks as if the wires go into the male end of that plug, and that I do have to cut them.

I'm going to be putting on some new bedsides, and don't want to make my job harder later....

thanks in advance....
