e23 headunit install (fader)

[brickwhite]

Putting VDO/conti headunit in my e23,



This is the fader my e23 uses.

Do I just us the the 6 wires that go to the fader using one wire as ground?

OK, so I'll run new wire each with its own common wire.

But for my power antenna (OE is a White Wire), I should just plug that into A5?
