I don't know the contacts by pin number and looking back at previous posts on this thread I see some misinformation. I am not an expert but I know what works on our trailer. Look at the picture below. Place your circuit/wire/fuse between the two contacts on either side of the bump and the running lights will illuminate. Another cool thing to do is place a hazard flasher relay between the two pins to make your running lights flash on and off. Drives the campground neighbors crazy!
