2015 Xl883 iron - Red/Amber LED run/turn/brake

I bought some two-color, dual-intensity LED turn signals for the reao of my bike.

When wred correctly:
The running lights are a normal intensity red.
The brake light is a high intensity red.
The turn signal is a high intensity amber.

The motorcycle is a 2015 Harley-Davidson Sportster. It has no traditional tail light, only run/brake/turn built into the turn signals. So, here is my concern.
1. See the picture labeled “Main Harness to TL Harness Connection”
a. Ignore the License plate light as I have no issues.
b. Notice the wires that feed each turn signal.
i. Ground – black
ii. Run – blue
iii. Turn Signal - blue with brown stripe
iv. Brake – blue with red stripe
2. See the picture labeled “TL Harness”
a. Notice that only three wires are used to fire each turn run/brake/turn lamp (1157 style bulb is stock)
b. Compare the number ID for each wire in “Main Harness to TL Harness Connection” diagram to the numbers in the “TL Harness” diagram.
c. Notice that the “”brake – blue with red stripe” wire is not used.

· This is strange because the brake lights work as normal even though the specifically-labelled brake light wire is unused.
· If the TS high-intensity signal is fed by the blue/brown wire, which wire is feeding the brake light’s high-intensity signal? How would I measure the outputs? Is it multi-stage voltage (6v/12v) or a second 12v signal feeding a second circuit?

Has anyone succesfully wired two-color, dual-intensity lights?

Thanks,
