Hi all, trying to fit an aftermarket head unit in the polo. I’ve read a heap of threads and I think I’ve got it, but still a little uncertain.
I have the pioneer wiring harness and a connects2 (CT20AU04) VW converter harness.
So on the pioneer harness yellow is for constant 12V power which matches the yellow wire on the converter harness, and the black ground wire matches up on both harnesses. So all good with those two. Do I still need to screw a wire to metal somewhere from the head unit for the grounding?
Then there’s a red wire on the pioneer harness for accessory power. So I need to splice in to the ciggie lighter or somewhere ignition switched for that one?The red wire on the pioneer harness lines up with an empty spot on the converter harness… so this is obviously where i'm forced to tap into other wires. Right?
Then finallythere’s a blue wire in the VW converter harness that matches according to an internet search, the switched/ignition power into the RCD200. Which makes sense because it’s also shared with a (powered) aerial adaptor on the harness.This lines up with a blue/white line on the pioneer harness. In the pioneer manual it says 'if the red wire is connected to an “antenna control type” then connect this blue wire. If it is any other sort of vehicle, do not connect the blue wire'.. So I think I do want to connect the blue wire.. right?
thanks!
