2014 RT-S BRP trailer wiring advice/ or part number needed

[billybovine]

Do yourself a favor... toss out the 9 pin harness. Buy the Big Bike parts harness. It is so much easier to wire than the BRP stuff.
I did it recently and it was a dream to install compared to the BRP stuff.

FYI the $429 to install is the old BRP 2010 trailer harness. BRP changed it later and it's about 1 hour now. BUT dealers don't get it and thus charge the full original labor costs of the old harness. I have heard this for the last 2 years now about people SHOCKED about the $400 to install the harness. Some dealers just do not know IT CHANGED FROM WAY BACK THEN and is a easier install!

Your mixing old and new harness convo's.

Bob please explain how the big bike parts harness is easier to install than the BRP harness. One connection for BRP and 4 for BBP. :dontknow:

What I mean is, it is easier to install than the old 2010 harness.

But if you bought a hitch and it did not come with the harness, the BBP is a easy install and much cheaper.

Sorry for not being clear.

SO....I'll need the Big Bike kit, and then I must still get a 5 to 4 wire converter and then the plug ends?

I'm starting to think I should have bought the Corvette!

I don't understand your reason for going this way. Get the 5 to 4 wire I link above for $35, a flat 4 plug for about $2. Use the Y harness you have and whack off the 9 pin connector, splice on the adapter, change the trailer plug to flat 4, and you're on your way! No messing around with the wiring at the taillights. Just plug the Y harness into the bike harness and route the cable down to the hitch! Routing the cable may require removing a side panel but that's not a big deal. And you have to do that anyway to use the Big Bike Parts harness! Save about $45 this way!

But, whatever floats your boat!

My aversion to this way is that the 9-pin connector also IS the isolator. Cutting that off means no isolation of the trailer from the Spyder doesn't it?

I actually am thinking of something totally different.....I am thinking now of mounting the "Y" harness I have exactly like it is. I have found someone on the Sale/WTB forum who has the trailer side 9-pin connector he cut off his trailer. I have a Spyder-side 4-pin plug. NOW....my thinking is put a 5-to-4 pin convertor between the 9-pin trailer-side and 4-pin Spyder side and I have made a 9-pin to 4-pin convertor that will go between the Spyder and the traile with all the proper genders and no cutting/splicing of anything except the "adaptor"! OR, do one of you guys see a fly in my ointment?

The harness from eTrailer is an isolator as well as converter. Some earlier BRP isolators have been problematic. I don't know if the one you have is one of the problem ones or if it was the later design when they used a 6 pin connector for a year.

Keep in mind the 9 pins of your connector are really the pins of a 5 wire harness. It's from that point to the trailer you need to have a 5 to 4 wire converter. The 5 to 4 wire converter is not simply a rearrangement of wires reconnected from 5 wire to 4. It is an electronic module that splits the brake light signal into left and right wires and combines them with the left and right turn signal wires. The eTrailer module, as I read the description, is both an isolator and a 5 to 4 wire converter. That's why I'm encouraging you to use it, spliced to the Y harness you have.

I think I now I see what you're thinking. Use the isolator/9 pin connector you have. Plug the trailer 9 pin connector into it with a 5 to 4 wire converter between it and a 4 square connector. The 4 square then connects to the trailer harness. But, you still are going to have to buy a 5 to 4 wire converter. 5 to 4 converters are available at NAPA as cheap as about $15. Amazon has the same item as eTrailer for just over $40. It's Hopkins 46255 Power Taillight Converter.

Another hitch with using the 9 pin connector you have. When it was being used by BRP they had a hole underneath the left saddlebag to mount it to. That hole is not in your bike so you will have to jerry rig some sort of mount somewhere.

I wondered where that large module with the isolator was supposed to be mounted. I think you and I are on the same page. I wonder too if the module I have is the problematic one but, it's worth a gamble before cutting out the good parts of the "Y" connector and going with a different isolator. I've got a few busy weeks coming up with no weekend to speak of so as I said, I'm in no rush and I'll have time to think this out.

Thanks again,
