    if you mean the wiring connector, it is very possible. ill make sure it is secure later. but the switch itself is on the service light setting, i was driving around with my headlights on, signals etc, worked.

    Now wait a minute here. The relay would not be clicking if the black out switch was the issue. With the switch in B/O the relay gets no signal. I am not an electrical genius but I do know the signal goes from the clicking relay to the horn. Not back thru the B/O switch. Come on you have other issues. obi wan Kenobi where are you?

    You may have misunderstood. These were 2 different things. Horn is fixed now. The black switch was causing issues with the brake lights.

    Still have some thing s to deal with but the truck was inspected yesterday and passed. It is now registered, insured, and on the road. 😁

    The brake lights are the other fuse that is on the 30 amp fuse that runs the lights. If you have a hot 30 amp fuse midway up in the fuse box the only other fuse on that leg of the fuse box is the brake lights. Without being there I am guessing but I had that issue in the past. I was at the inspection station feeling all happy and they came out and said no brake lamps. I was pulled from the list and my vehicle was set aside. I quick went out and messed with a few wires and jacked 12 volt into the fuse blade and called the mechanic back outside. I showed him it had brake lights. He applied a sticker and I drove home removed the fuse box and tapped an in line fuse into the fuse box. My 30 amp leg was just crumbling slag from being overheated may times and I was pushing barbed spade connector in both sides of the outside fuse leg. Made heat more and more over time. I was so good at knowing when the fuse blew I could put my foot up there and just push around on the right side of the fuse box top correct the lighting issue. Worked for a long time then one day. No good. Good luck. I like to share and brain storm issues. It helps. Anything is possible given the right conditions.
