Default wiring turn signals

I have a separate led strip for my tail/brake light and some led turn signals. Its all wired up and works however when I pull the brake lever the turn signals light up with my brake light. Is there a way to avoid this? I just want my turn signals to blink, not light up when i brake.

Sounds odd! Do the indicators work OK when you turn them on? If they do you may have mixed up the power and ground wires for tail/brake and indicators.

Is this how it was supposed to be (ie. did you or someone install a run/brake/turn module)?

Its acting like the signal wire for turn signals and brake light are all coming from the same wire. Each set of wires (there is 2) has 3 wires inside of it. Black, blue and purple. Black is ground, blue is signal and purple is constant. I can wire the new turn signals just like the stock ones just without the constant and those are fine. Now when I go and wire up the third light (led strip) I have a constant, signal and ground coming from that. So I match the ground and constant together so I have a tail light but when I wire up the signal wire to the led strip it blinks when i turn my blinker on. Its almost like I need to splice to the led strip to the signal wire coming from either the brake lever or brake pedal.

I'm assuming there is a wire coming from each of those that meet up under the seat somewhere at connect to each other into the stock wiring harness.

I know its confusing, I hope someone can make sense of what I'm explaining. If you can make sense, is there a wire coming from the lever or pedal that I can splice my signal wire of the led strip too?

He has a newer sportster that comes stock with a run/brake/turn module.

The purple wire is a combined brake/turn until you take the module out. It is above the battery, under the frame. A small cube looking thing that the two 3-wire harnesses go back to.

This post will explain it a bit:

Ok thank you, I'll go check it out. So i can wire the brake light and turn signals all before the module, correct? Or I guess I could just splice in the wire I need for the brake light and leave the others how I have it, just depends which is easiest.

sorry forgot to reply to you, I am unaware of what a module is.

you also might need a load balancer for the LED.

just splice in the wire u need for the brake light
and leave the others how u have it

do u have a a photo or link to the brake light ?????

under the seat look for red/yellow wire


splice the (+)brake light wire from the new led light---- to this wire
this will make it come on when u brake

if the light comes with running light as well
splice the run portion of this new led light into the blue wire under the seat
this will be the running light

No you cant separate it, the brake and turn signal use the same wire. Not without adding a relay on each side.
