Hi

I installed 3-1 aftermarket and was able to get the running light and signals working. However I can't find the brake light source. The one I think it is if I connect I get brake light steady on.

By looking at these attached pictures, can someone figure out what I'm doing wrong.

The wire you are looking for is Red/Yellow. Depending on your new lamp you may have to take either the indicator or brake wire from the in side of the module otherwise you will probably have a confusion with the indicators and brake. Here is a wiring diagram that may help.

The black is ground, the blue is what you call over there running lights, the orange/white is also lights usually used for license plate light if used, and the red/yellow is your brake light. I assume indicators are on a different plug on the aftermarket? I can only guess at your aftermarket one as many are different. I would think that black is ground, probably red for brake light and yellow or blue as running light. I am not sure why you would have 4 without knowing more about the light. Did it not come with any kind of diagram? The orange/white you do not need to use, many US spec Harleys do not use this wire, mostly for European. If you have a permanent 12v on the red/yellow as per your other post then this is wrong, you have a problem somewhere.
Do you have any info on the light that I can check out? Most of the ones I have seen only have 3 wires if its just a tail light and 5 wires if it includes turn signals.
