Default (2012) FLHTCU Tour Pack lighting wiring

(photos shown go from connection to Tour Pack, down left side to under the seat, and to where the connections are under the rear fender/rear tail lights/turn signals).

Bought this Ultra Classic recently, some stuff was done to it though all I was told about the Tour Pack (photo #1) was the antenna were relocated to the bottom left rear of the saddlebag.

Issue: the main lighting bar doesn’t display turn functions. The side lower/underside light strips act as brake lights, but also not as turn signals. All the lights work as running lights.

I see only one cluster of wiring coming from the lighting into the Tour Pack on the left side. and someone has labeled L, R, and C to each of the sections, which suggests SOMETHING was done (or why label them?).

I count six wires total (photo #2). I also count six wires under seat (photo #5) in the connector back side going to the rear of the bike, but only THREE wires coming from the Tour Pack (photo #4, bottom) to that connector.

And therein lies the problem it seems. I don’t know why I have three sections that seem to be able to act as run, BRAKE, and TURN signals, yet only function as running lights. I’m not a great ‘wire guy’ at all - figuring it out, testing wires, etc. No clue why the Tour Pack has those yellow, black, and blue wires with the blue tie in clips (photo #4).

I WANT MY BRAKE LIGHT AND TURN SIGNALS. What was done? Is there a plug-n-play wiring harness to replace that non-sensical section of wiring with?

Go here to look up your bike where you’ll find the tour pak and wiring harnesses along with part numbers:

Go here for wiring diagrams. You should also have one in the factory service manual:
