My truck came with a trailer brake control box when I bought it, the light showing it worked never lite up so I figured it was missing a relay or fuse, no biggie my trailers didnt have brakes anyway. Well my race car trailer I just bought has brakes and they work so I went to find out what is wrong with the box. I hooked the trailer up and all the lights work, but no brakes. I checked the relays and fuses, relay 203 was missing, replaced it and still nothing. I check relays and fuses # 5,101,108,201,203,302 and all seems well. But still seems like Im getting no power to the box, anyone have any suggestions?

 

Nevermind, problem has been solved
