okas a fellow 929'eri need ya'lls vast understand of wiring (im assuming and hoping) you will know about the stock wiring for the tail light assymbly . there are 13 wires6 solid greens,3 browns, 2 greens/yellow, 1 baby blue and1 orange. now all have a green that attach to them (R turn, right lamp, lp light, left lamp, l turn) which leaves 1 green left over ... now i believe the green acts as a ground wire but this one doesnt.. when i hook up a test light with a power wire and touch it to every other green it lights up except for this mystery green one. even on the wiring diagram it doesnt show a 13th green unless ofcourse im a complete dumb *** and can't read the diagram correctly.. so please if you know what im doing wrong please tell me !

and here is what i have to work with (all the female connectors on there i added trying to connect them to the factory bulbs)

 

AH! jumper wires. damn engineers!!!!! why do they gotta make everything hella complicated... now that we have this it's gonna take 20 mins man.. We need a little spare wire and some connectors

i'm gonna come look at your brothers Truck too

Thanks for who ever provided this

 

that would be letsride

 

Ready for this?

Okay, here it goes:

I'm thinking your "extra" greenis a main ground wire.

I looked at my bike and I have 12 wires as the book shows. I took some pics, lemme know if you want them posted. I doubt it will do you any good though, as my wires are still factory wrapped.

It's my belief that the 13th wire was once part of the 12 but since someone cut it to install the LED taillight, you now have what looks like "13" wires.

What you need to find is which one of those grounds is the main ground that the other 6 ground wires are tapped off of.

You could consider all those black dots in the diagram as "intersections" where the wires are spliced in somewhere within the harness.

I'm not sure how far down the harness these splices are, but that's what I see and if youfollow my logicthen that would giveyou 13 wires...1 main ground coming in which distributes to 5 grounds and7 color-coded which distributes to the corresponding lights.

So let's do the math 1 (main ground) + 5 (one ground for each light) + 7 (color coded) = 13

There was a comment you made in the other thread about this issueaboutyour test light and one wire in particular that lit it up...there was something about one wire.......I don't remember exactly.....whatever the case, isolate that wire and figure out if that's the main ground.



DISCLAIMER: I could be totally wrong. This is my thinking andthe wayI got to 13 wires.

 

Found your test light comment:

Did you do a continuity test from this wire to frame ground? If it beeps out then I'd say that's your main ground in the harness.

 

i agree with you that is what i thought ... at first but the length at which i cut off the factory covering to get to where i am now would be not only un logical but a total pain in the *** for someone to add an extra wire. i cut about 6" off the factory covering to get to "fresh" wires and still have that 13th all the way down.

 

I take it this thing isn't straight yet?


Are the turn signals working?

You mentioned something about the brake lights being "ON"....are you sure you're using dual filament bulbs?

Should I consider unwrapping my harness to figure out where the 13th wire comes in? (please say no)
