W203 '05+ Radio Wiring Diagram?
Does anyone have a wiring diagram for a 05+ w203? I specifically have a 2006 c280. Been trying to install a D3 all night with a VW03B harness and cannot get it to power up. Thanks

there is no switched power behind the stock radio. You will have to get it from the cig lighter. Also, if you have H/K sound, then you will have to run speaker wires from the d3 to the rear right of the car where the amp is located.

also should i cut the acc+ wire that i have wired to the harness? and just wire it straight from acc+ from cigarette into the pioneer harness? i'm not sure if i should keep the wire intact between the harnesses and just splice in, thanks

i've read that if you switch the '12v' and '12v switched' leads between the VW03b and the aftermarket radio harness- that will fix the problem w/o having to tap into the cig lighter. true?

Bringin back an old thread, but I need to know which wires are the fiber optics to the amp and which are the speaker wires. If anyone can help me that would be appreciated.
