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.

I took off the little square relay thing. So my plug is the one pictured below in the new attachment. it has 4 wires going in. blue. orange/white. red/yellow. and black... would you be able to help with what these are?

but coming out of this is only black, red yellow and blue...... no orange white

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.

Very helpful thread on explaining the wiring! Much appreciated as it allowed me to properly install and aftermarket tail light on my 99 Harley Softail! Thanks.
