Hey guys, new to the Harley world and to this forum. I just picked up a 2019 RGS. Love the bike, except the taillight. I live in Canada, so we have the big taillight on the rear fender. I managed to pick up a US rear fender to match my billiard blue off eBay. I’ve been searching the forums and cant find anyone that has done this before. I know the wiring harnesses are different, but people also get the CVO fender and make that work, which would be similar to this. Just wondering if anyone has done any wiring related to something like this? Thanks for the help.

So I have my US fender and plugged it in. Everything works except the brakes. Running, TriBar, license plate and signals all work. Anyone on here have any idea what wires should be changed to get the brakes working? Thanks!

More info. I’ve tried switching plugs around and still nothing. Although now, when I plug it straight into the harness on the bike, I only get the right signal to light up. I plug the factory rear lights in and they all work, with signals and everything. Any help would be great. Thanks

You are dealing with the harness that was already on your bike correct? Only the fender with the lights was changed?

Correct. The main harness on the bike is stock. I’m using the rear lighting harness from the US fender. I know the wiring will change slightly, due to the lack of a centre taillight and the TriBar light.

Just to be clear on this. With the US fender harness plugged into the Canadian bike harness you have everything working except for brake lights. Is that correct?

Well, when I first plugged it in, yes. But now, I have a code, which I cleared. Now the only thing that works is the right signal and i thinks it’s actually both filaments on. So brake light on right side and that’s it. I figured the bike probably powered everything up first and then shut it down.

Got a manual and a test light? I would figure out what wire is for what on the bike side and make sure it gets to the corresponding wire on the fender harness connector.

I just downloaded a wiring harness diagram. Going to start testing now. I believe the wires swap to different pins at some point. Thanks

Exactly. You might have to pop the terminals out of the fender connector and orientate them differently to catch the right signals from the bike harness. Good luck!

It’s weird. The Canadian and US show different wiring from the lights into the fascia converter module (TriBar) but they both come out the other side the same and into the bikes main harness. That’s the part that’s stumping me

Your statement is dead on correct with the wiring. Check your fuses just to be sure you didn't pop anything and rule that out just to be sure. Be sure the converter module is correct as well. The first 2 pictures attached are the 1) US converter out plug and the 2) Canadian converter out plug to show what the orientation is for the connector. The view is as if you are looking at the terminal side of the connector. The last picture is the harness into the converter. Good luck, let me know what you come up with!

Still a no go. I’ve been working on it all morning. Scouring the internet and trying different combinations of the wires. The only thing I can get is the right signal and the right brake to work.

US harness BE/BN to Canadian R/Y gets the right signal to work. Then if I connect the BE/R the brake lights will work with it. All on the right side. I swear if I get this figured out, I’m going to make a harness and start selling!

Have you checked all your signals coming out of the bike side harness to make sure those are all there? Check that first, then move forward.

Everything from the bike works. It’s the trial by error for the rest. But with deleting the taillight on the Canadian version, some wires may have to tie in together. I’m just wondering if the bike has to be flashed for this to work as well?

It could be possible the BCM needs to be reconfigured. If the bike was in front of me I could make short work of this but it's hard to do it this way. It could be the BCM is shutting down certain signals because it senses an open or a circuit over current condition. Keep at it, I'm confident you'll prevail or at least get a firm understanding of the system.

Still haven’t figured it out. I had an idea of using a trailer wiring harness. We used to use those on sportbikes when we removed the signals and used the 2 bulbs in the brake light as brakes and signals. Might as well try that next!
