My rear light & brake light aren't working. The wiring underneath the rear fender looks like a bomb site - tape and crimps everywhere. I've just taken my indicators (turn lights) off the bike, so I thought I'd investigate if I could tidy up the wiring.
Looking at the wiring diagram, I expected to the following wires heading out back; Red/yellow, Blue, Black (all for the Tail Lamp), black & purple (for turn lights).
However, what I actually see are:
- Orange/White
- Brown
- Blue
- Red Yellow
- Purple
- Black
So, what I'd really like to do is get my rear light and brake light working again, and if possible tidy it up by removing wires only used by turn signals.
All help gratefully received, as I'm really keen to get a few miles in over the christmas holidays!
O/W is accessory power and is probably not used.
R/Y is brake light power
BE is running light power
BK is ground
V and BN is indicator but don't know which side.
Here is a wiring diagram for the rear lights on a2009 Sportster, sorry about the poor quality, I ttok the photo with my phones camara from the H-D workshop manual.
Thanks for the list of what's what - that's really useful.
The diagram (reproduced below) is really interesting - the 6 cable slots on the rear light module are spot on in terms of the colours. However they are also replicated going out to the lamps - as you can see in the pic I posted. Which got me wondering - that diagram shows 3 different exit areas - one for each of the indicators and one for the rear lamp; that's clearly different to mine (again, as per pic). As this is a 2008 diagram, is there one for 2006 and 2007? I'd look myself but it looks like it needs a login of sorts....
thanks in advance - I'm really grateful for your support!
Are you sure there isn't a misprint, the Isn't the V (violet)wire for left signal and BN (brown)should be right? The colored diagram seems to have subbed V for BN on the right turn diagram.
My wiring diagram (granted it's 1991) shows brown wires to right signals, violet to left signals. Front signals are frame grounded, but use a BLK and V and BLK and BN for left and right. BLK wire is running light power. Of course, maybe the individual signals are wired the same colors from bulb to connector for universal installation, and the use of a BN wire ends at the connector block.

There isn't a mistake i=on the coloured wiring diagram, both left and right turn signal lamp units for 2009 HDI Sportster share the same part number, 68978-00 which has black and violet wires. The socket that they plug into has the correct coloured wiring for their respective sides, black & brown for the right hand and black & violet for the left hand side.
