Wiring for triple beam
yeah for sure I know that part, curious about the wiring part, did you need to strip or re-wire anything from the triple beam headlight or is it an exact plug and play?

According to the wiring diagram they are different. You need the headlight module, one for each headlight if you don’t already have them and the module uses a different connector type. So you have to figure out how to make a connection between the old harness to the new connector on the module. Not sure how the others did it but I bought headlamp wire harness for my MY 13-15 and the connector (x2) that plugs into the headlight module. I plan on splicing the two together for a clean install. As far as wiring goes try following the Russian guy’s diagram mentioned above. This will get you started, any issues with dash lights or parts of the headlights not working will probably have to be sorted out thru some kind of programming by third party or dealership.

Still in the process of getting all the parts. Once I have everything and have the wiring done, I’ll post pics. Please note this might be a couple of weeks, since I have other priorities that are more important at the moment.

It is hard to explain everything. You can google search how to program eeprom. Also I had to re-wire my dash harness. There was so much of work.

I was able to light up the headlights and this brings me to the next step. I will greatly appreciate, if you correct me with my next steps plan.
After carefully reading Russian guy's blog I found myself on the step, when you give +/- and IG to the headlight, it tries to communicate with Body MPX ECU, gets no feedback from Body MPX and lights up low beam only. And he recommends two ways to fix this:
1. Wire up everything like on his schematic, program Arduino + can shield to generate Body MPX feedback, connect it to the CAN bus and everything should work (DRL, low/high beams).
2. Alternatively, wire everything as he recommends but instead of connecting CANL/CANH to Arduino connect these wires to Body MPX. Before that, Body MPX needs to be swapped with a newer one from 2016+ GS, but with EEPROM copied from the old ECU, because newer Body MPX has different processor code, designed to work with new headlights, but and all region and car settings are stored in EEPROM.
And, yes, headlights' + should be connected to headlight relay pin 3 or 1 to get constant +.
Does this all sound about right or close to what you have done?
