Got the Kuryakyn Universal Run Turn Brake, any have been reading thru prior posts about which color wire matches to which.

My main question is where do I splice this thing in at? If looking at the two white connectors under the seat, do I splice it into the taillight segment of the harness (shown with green wire), or do I splice it into the headlight portion of the harness?

This thing is supposed to be easy I suppose......

Tail light portion.

Good advice here.

For some reason the wires change color at that connector. Tap into the wires that go to the tail/turn/brake lights.

Posi taps are a great way to tap into a wire.

You'll have to find out if you are supposed to run the controller in series or parallel first. If in series you'll have to cut wires. If parallel, you can use wire taps/posi-taps.

I recently did a write up for black out tail lights for another member. Check out post 16 for a wiring diagram for the rear lights.

The Universal RTB is wires go inline, except for the Power, that taps off the existing wire without splicing.
