Im just putting in my electrics before carpeting, I’ve got a loom for 6 spotlights (probably should’ve got 8) I’ve run the wiring from side to side for two and then along the side to the next spot for the the row. The trouble is it seems to limit the positioning of the lights due to length in between each set of lights (it’s a pre built loom from Rayne ) My question is can I just run the wires front to back down the middle of the roof as long as I avoid the areas where the roof will be pinned? Is there a suitable gap between the roof and the top of the van?
