fog light question
#11
I found the wiring diagram and here is what I came up with....
The FLHX does not come pre-wired per say for the aux lamps, there is no extra plug for this I'll explain...
The plug for the turn signals is on the bike between the fork tube and the hole in the back side of the mounting bracket for the turn signal.
It has 4 places for wires, 3 are being used for the turn signal plug, the last place has a waterproof plug in it. These are plugs 31RB and 31LB and only 3 wire connections are shown on the wiring diagram, wire 1-3. The wire colors are , #1 is blue , #2 is violet brown , #3 is black
On the diagrams for FLHR/C and FLHT the #4 place is for the aux lamp. The return shows it to be chassis ground.
The aux lamp switch on the left switch pack goes to the BCM on a be/gy wire and comes out of the BCM on be/bk to #4 on plugs 31RA and 31 RB
For the FLHX, this would be where the feed for the aux light needs to go and in my case where the new fog lights would need to go.
I would also need to put the Button/ switch in the left switch pack to send power from the Aux light output contact in the switch pack to the Aux light input on the BCM.

The switch bank for the left side of the fairing is 69200173 and the cap with the aux lamps icon is 71400044 and goes into the leftmost position. That's all plug and play.
It couldn't be any easier to add aux lamps to FLH's and FLT's that don't come with them.

Someone needs to just buy the harness and lights and install it all! You don't even need to understand it to do it. As an aside, if you have a halogen headlamp, you are going to want to replace that with an LED so that the colors match. The Harley LED fogs are white and they really bring out the yellow in the halogen headlamp. Also, I followed the directions included with the Harley LED headlamp and switched the headlamp setting from dual halogen to standard. The fog lamps go out when the headlamp is on high beam.

You can still use the same procedure and harness for non-Harley lights, no custom wiring needed except maybe where the wires connect to the lights. You don't need to connect to the side panel unless your lights draw higher amps than the Harley lights would. I did this on my 2019 RGU, all plug and play with non-Harley lights.

If you want the passing lamp indicator in the instruments to turn on when you switch on your lights you'll need to get that feature turned on in your BCM, either by the dealer or by using an aftermarket BCM programmer such as TechnoResearch. This is optional.
