The ISO-Connector is just for the power-supply, amp-remote, dimmer etc. (Be sure that the pins are the same as they are on the empeg - i have a french peugeot and I had to rewire 2 pins..)
You'll have to connect the amp audio-input via 2 stereo chinch cables with the empeg (there are sepparate outputs on the docking cache)
Is the AMP (remote) already connected to the ISO-Connector? In this case check if it's on the correct pin which will be fed by the empeg.
If that's not the case you'll have to connect the ISO-Connector with the amp-remote line.
The description of the pinouts of the empeg you'll find either in the manual or somewhere in the FAQ. The description of the car's ISO-Connector you shoud find in the car's manual or maybe on the factory car-audio itself or you could ask your dealer.
Everything clear? Hope so...
