97 Sportster turn signals
I bought a 97 Sportster 883 (w/big bore kit) from a friend and it didn't come with turn signals. He said he got it that way and just used hand signals.
I wanted something more so I bought led mirrors that came with these little circuit boards with a bunch of wires and heat shrink over everything, and a lot of connectors. I took the heat shrink off so I can look at the board. On one end has a connector the old lights would plug into. Then it has a fuse on the positive wire. Then the circuit board then 6 wires out from there. 1 Red, 1Blue, and 1 black with male pins, and the same with females.
They are labeled: Black = GND, Red = TSM, Blue = RL
(I'm assuming GND is Ground, TSM is Turn Signal Module. Is RL running light?)
I've tried looking online for info but I'm having a hard time figuring it out. I tried wiring without it, but the turn signals do not blink. I can turn them on and off by pressing the turn signal switches, and if I hold both down the flashers work.
I even picked up some cheap bulbed turn signals, and wired straight to the turn signal model and got the exact same results.
I even ran through the troubleshooting on my factory service manual but it says to replace the module.
The closest I could find relating to this on the forums was this post: https://www.hdforums.com/forum/sportster-models/932480-sportster-68540-96-turn-signal-module.html
The module part number is: 68540-96

Harley wires And for fun, my bike
Thanks in advance if anyone can point me in the right direction.

If you just wired up the led signals on front and nothing else they're not gonna work. I just went through this on my sons 98 Sporty, it didn't have rear signals when we got it and front wouldn't blink. We put led rear signals on and still didn't blink but hooked up incandescent bulbs and they worked. We had to add load equalizer to get the signals to flash with leds.

That's what I was getting at. Make sure you have all the incandesents wired in. Otherwise your bike will detect low resistance and "think" you have a bad lamp.

I think this is the one you would need Chris, if you felt like spending $95 +/-.
