trailer light problems

[kodiak024]

I'm having with my wiring to the trailer, first I needed to up my amps in the fuse block to the brake lights by 5 amps and then to the blinkers by 5 amps. without uping the amps they of course would blow out, also when you disconnect the trailer it blows out the brake light fuse? wtf also this is a rental trailer and the wiring on the trailer is correct, oh yeah one more problem there is no brake or blinker lights on the trailer but the running lights work, I hooked the trailer to another truck and it worked

I would use a multimeter to see the readings on the plug on your truck to see if the brakes and turn signals give something out.
Does your set up use those plug-in wiring harnesses? You could check the connections on that.

connections

yes I checked the connection on the plug in harness they are good I have not checked the voltage out to the four because well like i said I hooked it up to another truck and the trailer worked fine

The plug in harnesses usually don't go bad because they are sealed pretty good but you never know. What is odd is that you bumped up the amp on the brake fuse and it is blowing out. This might mean thare is a short somewhere but I assume this didn't happen b/4 you hooked up a trailer.
I hope others have some good ideas.
