Tried to splice in the running/brake/signal lights on my headache rack this weekend and ran into trouble. I tried to tap into the wires coming out of the back of the 7 pin trailer connection just the same way it had been done on my previous older truck, but this truck recognizes the extra draw on the system and makes the computer think I have a trailer plugged in now. From my research, I could buy a special harness from “Magnum“ or something, but it’s like $265. Anyone else run into similar situation and find a cheaper alternative?
