Default Installing USA front turn signal assembly on a UK FXBB streetbob

Hey all,

So I have a U.K. 2018 Streetbob FXBB. The front turn signals here are single contact type 1156 which only have two cables and no running light.
I have purchased a pair of RRi SigZ V2 Front LED which have the the US/Canada dual contact type (1157) and of course, won't fit the UK bike.

I have therefore also purchased a set of UK/Canada front turn signal assembly (HD part 67800147) which will take the 1157 dual contact LEDs. This has tree cables, which I assume is for the running lights which is not the standard for the U.K.
I am having trouble determining the exact wiring for this assembly. I can make a direct connection with the initial two wires but not the running light.

Can anyone provide direction on how to go about wiring this assembly onto a UK bike?

Any insight is appreciated

Bring the running light wire to an ACC. connection.
or the running light connection under the seat for the rear lights.
or follow the wires back to where it connects. Harley isn’t that nuts that they iliminated the run wire from the main harness.

Wiring diagram shows:

Right Ft
1-BE
2-BE/O
3-BK

Left Ft
1-BE
2-BE/PK
3-BK

Black = ground, blue = running, and blue/stripe = turn. The 4 pin connector is labeled 1-4. Only pins 1-3 are used.

The bike harness will have the appropriate wiring, however I'm not sure if the ECM needs to be flashed to enable it. In my case, when I added an additional rear run/brake light, like what a proper tail light would do (mine only had two sigs running as run/brake/turn, no middle tail lamp) I added the brake pin to the existing connector under the seat and everything worked as I had hoped.

What is normal for your bike (with the two wire config)? - sig light off normally, and only on when flashing turn signal? Then adding pin 1 on the connectors should add running light. Should...

Connectors should be just behind the steering head on left side of frame under a rubber grommet.

And, thanks for pointing out those sigs. I just ordered a set. I have the Custom Dynamics equivalent, but the CD's only Illuminate the outer ring while in running mode, and the inner LED's when signaling. These seem like they will be brighter with all LEDs illuminating white.

I can tell you exactly how to do it.

If so, it's as simple as just plugging them in.

There are two connectors in the frame neck (one for left signal and one for right). Even on UK (and all international bikes), the wiring is exactly the same at these connectors as the US bikes. There is a ground, turn signal power and running light power.

You will have ABS on your bike, so you need to remove the screw clamping the ABS lines in from the the big rubber grommet in the frame neck. Move these lines out of the way, then gently prise the big grommet out. Once that is done, you can (again gently) access the connector block in the neck. You can pull it out of the neck far enough to access the connectors.

Unplug and deepen the connectors. then you can pull the wiring through the bars as you take the old turn signals off. Remember to attach a draw wire to the old wires so you can use it to pull the new wires back through.

Pull the new wires through the bars, plug them into the connectors and then plug the connectors back into the connector block.

Gently put all the wiring back in the neck, reinstall the grommet, attach the ABS lines and you are done!

You guys are awesome. Thank you very much! Soon as the lights pass through customs I’m going to give this a go and will report how it went

I wanted to this with a custom dynamics taillight but in my HDI fatbob.
my bike has a stock sealed rear run/brake/run light with a small led in the middle for turn signal.
i have been told that if do plug and play of the taillightit will only work as run/turn, or run/brake if I do some hardwiring.
Did you get your extra taillightt to work as un/brake/turn?


thanks

does the 67800147 has the full long wiring cable to connect it to the harness? Or it is just the socket?

Did you solve this? If so, what steps did you take? Thanks

I solved it using an american 1157 socket with its long cable. Removed 1156, passed the new one thru the hanldebar and used the socket housing that came with my 1156. I removed the cables from the housing and crimped the 1157 cables with new nj-19s connectors. The socket housing has 4 slots, so you need to check the wiring diagram to see which ones to use (dont remember right now sorry).
After you have done that, you just plug it back and that’s it. The main socket will provide constang power for the running light to work.

Hope this helps
