I have been searching for ages but can't find the answer..
I have bought a Kenwood KDC-W7044U and an Autoleads PCB404 connector.
I connected everything up and the headunit made a wirring noise as if it was trying to play a cd but nothing turned on.
I have connected the RCA's that came with the lead into the Kenwood and hear a popping sound but still the CD player won't power up.
There are 5 wires from the Kenwood, blue/ white, orange, red, black and yellow.
The red is connected to the red/ white on the a3 wiring and black to the brown on the audi but not sure where the others connect to.
Could someone please help??
