There is an ISO Conncetor out the Empeg : OK

I'm again victimized by a teflon coated memory... But IIRC, the ISO-adapter is delivered unconnected to the docking cradle - you get to connect the wires from the cradle to the wires on the ISO adapter.
Use a good crimping tool or solder+heat shrink tubing.

This means that it is easy to match up even to a car with a non-standard pin configuration in the cars ISO adapter. For instance VW/Audi switches pin 4 & 7 in the connector (switched and constant +12V).

If I connect both together, How my AMP (Alpine) will work (? : How control the Remote).

If your car has the 'remote on' wire in its ISO connector, you connect the cradles remote on to the appropriate wire in the ISO connector and then plug the ISO connectors together.
If your car doesn't have the 'remote on' wire in the ISO connector - often the case when there's no OEM external amplifier - and you installed it separately yourself, you have the choice of either connecting the wire in the car directly to the wire on the cradle, or using one of the (if there are any) free positions in the ISO connectors. In the latter case you might need to buy the special connectors that fit in the ISO connector(s).
