1999 FXR2 tail light issue

Posted this in the EVO forum, but realized here may be the better place...

I’m a fan of LED’s, so this evening I was installing some custom dynamics dynamic rings in the front sigs (waiting on the rears to arrive) and a Kuryakyn LED tail light (their model 5436) - normally I would get the CD tail light, but for my bike they only make an insert, and not a full LED housing. So while I’m not a fan of Kury stuff, they had a complete LED taillight for my bike.

So I installed the fronts, and noticed a “badlands motorcycle products” module under the left panel when I went to install the CD equalizer. I figured (correctly) it was a run turn brake module, since the bike had that functionality. What I didn’t know is that it also functions as a LED load equalizer, so I didn’t need the CD one I ordered. Anyway, heres the weird part. The Kury tail light lit up, but it looked like the brake was on all the time, and no plate light was on (it has a separate set of white LED’s on top to light the license plate -which should be on all the time). When I hit the brake, the brightness didn’t change, but the license plate led’s lit up (they are supposed to be on all the time)!?! I can’t imagine the badlands module having any effect, as the Kury tail is supposed to have the license plate lit up all the time.

So Amazon is exchanging it, hopefully I just got a weird one. But if it happens again, I got to blame the module. It’s hard wired so I can’t just unplug it, it’ll have to be uninstalled which will involve cutting and splicing, which is rather not do if I don’t have to.

Very strange.

Check the wiring, I found the WD at: https://www.namzcustomcycleproducts..../04/ILL-01.pdf
The tail lamp and the license plate lamp should be on the blue wire. Brake should be on the R/Y wire, O/W is a power wire and should not be messed with. The R/Y wire should have an inline splice along wiht the blue wire going to the module, the V and the BR wires should be cut and spliced to the module with the Y from the module spliced going to the brown going to the right TS and the Grey going to the Violet going to the left TS. If these are not wired correctly you may have an issue.

Sorry, posted this earlier on the EVO forum. Forgot to update here. Resolved below.

Very strange

So the diagram I found was nothing like how mine was wired. But it worked as designed with the incandescent 1157 bulb. So I broke out the handy multimeter and tested the 1157 socket at the tail light. According to another diagram I found, it was getting power where it should. It must be the Kury led lamp. I’m looking at it, and it had three wires. Red, blue and black. Goes to a connector. Kit comes with an adapter that plugs into the 1157 socket and the lamp plugs into that. So I’m looking at it and it dawns on me, the adapter has the red and blue wires reversed. Surprised I didn’t notice that when putting it together. Anyway, I depinned the connector and swapped the wires, so now everything lines up. Plug it in and everything works as it should.

So the connector was wired backwards. I can’t believe it made it through any QA check, but maybe none are done.

Oh well. Problem solved. Y’all were right about backwards wires, just in a surprising location!

Thanks!
