Just for grins, have you tried disconnecting the load equalizer? According the the website for the Turn Signals, "a load equalizer may be required" but since you have that installed and the turn-signal portion is functioning okay, try the lighting without the equalizer module.

Can't hurt really. Let us know what you find.
Bill,
I have wired it up w/o the load equalizer. The Blue (lead) wire overpowers the Purple (running lights) so it looks like the brake is permanently depressed. In which case the blinkers don't work.
I have also "criss crossed" the wires (i.e. Blue to Purple and Purple to Blue). In this instance the brake lights are always on and blinkers do work, although they are extra bright.

A 2017 bike designed for LED lighting where you have turn/run/stop in the same lamp the bike will have 4 wires to each lamp.
If the bike is using bulbs then there will be 3 wires going to each lamp.
If the bike has a central stop/tail led lamp 3 wires go to the turn signals for indicator and running only.
On some bikes there might only be 2 wires going to each turn signal.
Andy,
I thought so as well. I only bought the load equalizer for safe measure.
Once I wired up the LED tails and they didn't work properly, that's when I spliced in the load equalizer.
My '17 Sportster has tail lights that function as turn/run/stop. There is no central brake light.
The pig tails leading to the LED's are only three wires. Black = Ground, Blue = Brake and Purple = Run/Turn.
Thanks for your guys' insight.
I'm kind of at wits end here. I didn't think 3 wires would cause such frustration.
Blue wire is running light, purple is turn signal.
The BCM being some clever electronics is able to handle bulbs to give you running, brake and turn. Either the turn signal filament is used for brake or the running filament is driven with 2 different voltages.
As mentioned earlier if the bike came with led run, stop, turn then the lamps have 4 wires to supply each element individually.

You might need a converter module.
Yes, the new LED's are designed to work as running lights, turn signals and brake lights.
The original lamps were bulbs.
I figured the load equalizer would fix the bulb-to-led issue.

The BCM is able to learn what it is driving when it comes to the turn signals.
Program the BCM. 2014 and Later Touring and Sportster, 2012 Later Dyna, 2011 and Later Softail: The BCM can self-learn if LED turn signals are installed when the Hazards are active after the LED installation. The BCM ignores the first two cycles of the Hazards. It then learns during the next ten Hazards. After 12 cycles of the Hazards the setting are updated in the BCM.
Verify that there are no BCM codes. If codes display, see the service manual. Follow procedure for clearing BCM codes.

THANKS Andy!!!!
I will give this a try later today.
Will report outcome.
No dice! I tried a myriad of configurations.
After clearing codes and re-wiring multiple times, the same codes keep coming back. With and without the load equalizer.
B2151 - Left Rear Turn Signal Output Open
B2156 - Right Rear Turn Signal Output Open
Due to these codes, the BCM was unable to learn. I'm assuming.
Still a no go!
I removed the load equalizer since Andy mentioned the 2014 and later Sportster can "self-learn"
I wired the LED's straight up: Black to Black, Blue to Blue and Purple to Purple. Let it run for about ten minutes. Let the hazards cycle through for quite some time. No change. No "self-learning."
I tried again, but this time I crossed the Blue and Purple wires: Black to Black, Blue to Purple and Purple to Blue. Again, let it run for about ten minutes. Let the hazards cycle. Nothing. No "self-learning."
Still getting the following codes:
B2151 - Left Rear Turn Signal Output Open
B2156 - Right Rear Turn Signal Output Open
What am I doing wrong???
I've seen these exact LED's work on an Iron 883 of the same generation.
I can't be the only one with this problem. Help!
