I'm finishing up an upgrade project of a 98 Defender D90; I may re-attempt to go after that power cable for the Auxiliary Light Switch functionality today. I really don't want to remove the left side fairing panel and the speaker housing again, as I do remember finding those panels the most difficult to replace; especially the one coupling clip which kept falling down into the speaker cavity...
I'm also starting to think that I might have been triggering the MENU button vs the MODE button when I first attempted this project... I do like the idea of being able to turn the lights ON/OFF via the MODE button; I'll probably leave the existing switch in place and in the ON position, and let the LED indicator serve as the Auxiliary status indicator.

Yes I am tossing up the idea of biting the bullet and paying the $300 to get the switch, because I have a feeling the SA will say it can't be programmed from the responses others are getting on doing this upgrade.

OK - So I took the front fairing apart in order to implement the use of the MODE Switch in order to activate my AUXILIARY Lights; I'm looking at the following wiring pair:
Brown = Ground
RED/BLUE Trace = 12V NOTE: I get 12V DC for approximately 2 seconds when I first turn the bike ON, as well as when I start the bike; however, I don't get any functionality from the MODE Switch. Any thoughts? Is the RED/Blue Trace wire the correct pair?
Oh BTW - I found that after the BMW shop installed my Adaptive Headlight; I was missing two (A2) screws and a retaining Clip. This is why I prefer to do my own work whenever possible...

Look towards the bottom left of the headlight, plugged into the item circled in RED

I'm almost positive I have the correct wired pair; I had cut the connector off as it mated up with the wire harness that I used for the Aux/Directional lights..
I noted that my software version is the following; perhaps that has something to do with my switch not being enabled: 013_012_050

The wires in your pic look to be the same colors as the ones I used, so is there a connector plugged to just a cap at the bottom left of the headlight?

If @Scott Semone was unsuccessful in finding the connection for the Aux lights it makes me wonder how accurate are these instructions? I followed Scott Semone's instructions when I was actually doing my install.... Maybe different options or year?? I know others have stated the wire was under the tank, in my case it was not. The cable was just capped off to the bottom left of the headlight.

I was browsing FB R18Bagger page and I found a pic of someone elses bagger with faring off and I see the connection that is on mine circled in RED

The wires were originally capped off as a pre wired solution; today I only see 12 V for 2, maybe 3 seconds upon turning the bike ON and right after starting the bike; but no luck with the switch functionality...
This was the same thing I experienced back when I first attempted this in 2022; I was starting to second guess my instincts in solving these things... I'm convinced that my bike is lacking something that other bikes have??? Maybe an option is enabled via software..?
I put the bike back together and still happy with my original solution; however, having the ability to use the MODE switch was appealing... At the very least, I was able to spend some father-son time today wrenching on the bike...

Makes me think you had the right wires, because I do remember the lights coming on a few times for a few seconds when I first hit the power button.
