So I have had problems w/ my trailer lights and finally decided to try to fix it by tapping into the wires straight from the taillights. Looked good I had power and thought all was good. So now I'm gonna move my truck but when I tried to crank it the gages went all the way to the right then when I turned the key over all I got was a clicking sound if I turn the switch off and turn the lights on everything goes dim. I thought I grounded out or something so I went and undid all my work. Now I'm totally stumped. Anybody got any ideas.
