'86 Ford Aerostar Radio Wiring Diagram or Schematic

[hotdjdave]

Where can I find, online preferably or elsewhere, a schematic or diagram for the radio wiring on a 1986 Ford Aerostar?

This one has the remote control on the drivers side second row passenger seat.

The vehicle has an after-market Kenwood radio improperly installed and I want to fix the problem. I checked the internet and cannot find it. I found the diagram for the Kenwood, but not the vehicle.

Also, can the passenger remote control work on after-market radios or only OEM radios? Currently, the remote control only turns "on" and "off" the rear speakers.

Thanks,

DJDave
