Question: Burmester Amplifier MOST150 connector wiring





Can anyone confirm the functions of the small red, purple and orange wires and their polarity when active? (The two large orange wires are the MOST150 fiber optic cables)
(I've noticed sticking a grounded test probe in there will wake the amp sometimes.) A negative trigger?

I believe this is the W205 AMP wiring diagram for the connector but no colors are shown for the lines 1 ,3 and 4.




Then I switched to the Nav TV Zen M (and removed the oem amp) and it provides an on/off trigger.
can i connect them to the back of the head unit ? I don't have schematics for the original head unit connections.




Check YouTube and/or search the forums for someone who had base audio and upgraded.
Audiotec Fischer has plug and play kits, check their install documents for answers.
