I got a cooler rack from Larry carbon one trying to get the lights to work and I'm having no luck. I picked up a trailer wire converter has 4 way flat at one end to plug into the cooler rack and 5 wires coming out the other end. One for LT, RT, Brake, Tail and ground to wire to the bike. Note I have an RSTD. It seems I can only get the running lights to work when plugged into the cooler rack plug. If I just use a 4way flat at both ends I can get everything to work except Brake.
HELP what is the problem or what am I doing wrong. This is what I bought.
