I dunno about getting more wires into the door
I guess you'd have to have another harness to plug and unplug when removing the doors
good idea, but my doors are on and off too much!
What I did on my old YJ when I added power locks to the half doors was use a set of street rod style contacts in the door sill instead of running wires.
That also how the 3rd brake light is powered on my hearse (from the factory)
That might be cool....
one part goes on the door, the other the sill, and they make contact when you close the door, you can get 1-5 contacts
