Trailer Wiring MOD

[ceyer69]

I recently added the Can Am BRP hitch for my 2015 RT SE6 S and did not like the BRP wire harness. It would be a real pain to get to and get really mucked up with road debris where they suggest it be mounted. I came up with this and think it will be great. I used a 6 pin connector on the bike so I could extend a hotwire to the trailer for an inside light or an extra charging outlet. I used the Bike Bike Parts wiring harness and connected straight to battery to ensure no worries with the cluster. Sorry about the sideways pics!

NICE JOB!!

I am attempting to hook up something that's supposed to be simple, but seems to be becoming more difficult as I progress.

I purchased the Big Bike Parts harness for my 2014 RT SE 6 LTD, got it hooked up easily. When I tried to wire from the BBP y harness to the trailer 4 flat plug, I couldn't manage to get everything that the trailer should have (Running lights, brake, left and right turn and 4 way flashers.

I was told I needed to purchase a 5 to 4 wire adapter, which I have, but now I'm really confused. I can't get all the trailer functions to operate. I can brake and tail lights, but no 4 way flashers. I can get 4 way flashers without turn signals or brake. The last scenario I attempted gives me everything except 4 way flashers unless I apply the brake pedal. I am now lost.

So my question is, has anyone attempted this and how did they do it?

Can we see a pic of the trailer wire plug? Is the trailer grounded to itself in the wiring? I have heard some talk that are using the y harness that the trailer has to be grounded. Hope this helps!

The screwy setup

The trailer wire plug is a common 4 wire flat. The trailer has it's own ground, but it appears it also has to be connected through the white wire on the 4 flat plug to the converter.

I have been working from simple drawings to verify and correct problems. This is the one that seems to work the best. As you can see it is strange that a wire has to be spliced from one side of the converter to the other on each turn signal. That's where I get confused.
