Here are a few pics of my recent efforts. Since my tail lights are mounted in the rear doors, I chose to use Magnum Shooters to eliminate the need for wires passing thru from the body to the doors. I used these on my 48 because I had power windows and electronic door solenoids. They work great. They come in many varieties.

I also added a pos & neg junction post to my removable fuse panel. This will allow for a ground or power source for additional accessories.
One of my goals with this build was to do a better/more organized routing of the wiring than I did on my 48. I have rally tried to think this one thru.
Thanks
