Wiring sucks. Even electricians don't look forward to dealing with the bird's nest of coated copper hiding beneath your seat. Thankfully, British Customs has the solution. This turn signal harness features an OEM connector allowing you to simply plug-and-play your way to the aftermarket turn signal look you want. Equipped with 10mm bullet connectors and an OEM friendly harness, you can leave the electrical tape in the junk drawer.


  • Allows you to install aftermarket turn signals easily without splicing or wiring
  • Work with most aftermarket turn signals
  • Sold as pair


Note: Must use with BC Rear Turn Signal Relocation Brackets. Doesn't work in stock signal location. Does not work with Triumph America/Speedmaster for the front turn signals.

No need to solder wires. It was such a breeze installing my turn signals
Review by Kev Berns / (Posted on 10/6/2016)
Cake Upgrade
These harnesses made installing new indicators a breezes. These easily fit under the seat or inside the headlight bucket for replacing either set of turn indicators. With a coupe of zip ties you have a very clean easy upgrade.

Plug and Play
"I ordered these along with the Lucas Fender Eliminator and Square Turn Signals. Your new turn signal will have bullet plugs and likely wont just plug right in to your stock electrical setup. These pair of wires made plugging in my new signals easy (and they add a bit of length for easy of routing and relocation).

Absolutely a must buy with any new indicator set."

must have
if you are replacing any blinkers on your bike, this is a must have especially if you have the cafe seat. it allows you to remove the seat completely. makes blinker installs easy.

do I need this for the front turn signals?
The Turn Signal Wire Harness will allow the bullet or retro turn signals to be plug & play. Otherwise, you would have to cut and splice to connect.
