Exclamation Disconnect running lights from stop/turn at rear can?

1969 Overlander -

After installing an aftermarket LED puck in the rear can (single can type - shares stop/turn/running lights), I've got electrical demons popping up. Tow vehicle is a VW Touareg which has sensitive electronics. All other lights on the coach are already changed to LED with no issues.

Works fine with running lights turned off (daytime), but turn on your headlights and the VW senses an issue and blocks use of the break and turn signal (slight problem with driving at night like that!#$!) . We thought it was a voltage issue (too little) and installed dongles to add voltage to the line (Dan @ LED4RV). Not it. Pretty obvious that the VW does not like the running lights crossed with the Break/turn. Worked fine before but something about the LED voltage makes it overly sensitive.

My solution is simple. Cancel the reverse light in can #2 (clear lens) and change it to a dedicated red rear running light, then turn can #1 into a dedicated stop/turn. To do this I need to disconnect the point where the stop/turn and running are wired together for can #1. I presume that is at the front distribution hub where the tow line plugs into the coach? Can #2 has a line that runs front to back. I could easily switch this line and hook directly to running lights, switch clear lens at rear for a red, and then voila I have separate running lights and stop/turn at the rear.

Can anyone confirm the exact point where the lines for the stop/turn and running lights are connected that run to the rear can #1? Is it literally just crimped together or is there some device? If my presumption above is correct, its an easy fix. I worry that its behind the can which makes it much more complex, would require opening up interior paneling.

Thanks in advance!

Doesn't your VW use a separate bulb for turn signals? Whenever I see a problem like this, it is usually in the conversion module. Of course, with modern electronics, I may be telling you to chase a ghost, but it is something to check.

Meddle not in the affairs of dragons, for you are crunchy, and taste good with ketchup.
