What we did is ran 4 wires through grille along front fender then under car ty wrapping wires to anything we could some area we went through frame and finally drilled a hole in trunk for wires to come into trunk area,put magnetic lights on roof ran wires into trunk area, plugged them , in and was ready to go, then after trip I unplug wires in trunk and put mag lights and wiring in a separate bag with extra stuff , plug that hangs out of grille I fold over under hood, the extension cord I made that goes from plug by grille to rear of MH I unplug and store in same bag, that way nothing gets lost and it stays clean, as far as connections go We have used this system for yrs we went with LED lights even though we hardly drive at night during daylight hours they really show up good -Rich
