I have a 05 kingpin installed a universal plug in play harness for trailer.
the only thing that is not working is the trailer brake lights. I read some where that
maybe it needs to be wired in front of brake module on bike where ever that is?
Any suggestions would be greatly appreciated.

Download the service manual on MediaFire or on The Vic Shop site for wiring diagrams but I believe what you may be looking for is in the headlamp bucket.

So as a Pin owner myself, I'm curious of what kind of trailer are you pulling and with how much weight?
