Default Re: Wiring 'Aux-in' (iPod) connectors to Car radios

Disconnect the white wire from the tag on the volume control nearest to the push button tuner, but do not disconnect the capacitor wired across the two outer tags of the v/c. If you are not planning to listen to the radio, the white wire can simply be removed from the PCB and no further connection made to the board, but if you want to continue to hear radio programmes, either a changeover switch or switched jack socket is needed, wired as described in my earlier posts on this subject. As to the resistors, any value between 1 and 10k will be OK. Two resistors are needed, one connected to each of the inner cores of the lead from the 'aux' input, i.e. one to the LH Channel lead and one to the RH Channel lead. The 'free' ends of the two resistors are then joined together and connected to the tag on the volume control from which you removed the lead. The screen of the 'aux-in' lead does indeed go to the 'cold'(earthy) side of the volume control, which is the one to which the orange lead is connected.
