More on the Factory Sound System Interface
 
 
To replace the premium factory head unit:
Use one of the cables for aftermarket head units from list "A", such as the Kenwood 16 pin. One end of this cable plugs into the head unit and the other end plugs into the OEM-1. Then choose a second cable from list "B", such as the GM 12 pin for '84 to "90 Delco Bose systems. This cable plugs into the factory harness and the OEM-1.

Adjust the potentiometers on the OEM-1 and mount the head unit in dash. The installation is complete.
 
To replace the premium factory amplifier:
Use one of the cables from List "C" for the factory harness, such as Ford Premium Sound/JBL '89 & up. This cable plugs into the factory harness and into the OEM-1. The second cable is the AMP-RCA from list "B". This cable plugs into the OEM-1 and has 4 channels of RCA output (using RCA jacks) and the trigger lead needed to turn on the amplifier's).

Run RCA leads and trigger extension to amplifier from the AMP-RCA. Run main amplifier power directly from battery. Connect speaker outputs of amplifier to factory or aftermarket speakers. (Note: the Ford "ADD-FRD1" includes connector for factory speakers.)

Adjust the potentiometers on the OEM-1 and the installation is complete.
 
To add an amplifier to the premium factory system:
You can leave the premium factory system in place and add up to 4 channels of amplification with simple plug ins. Use a cable from list "C" that plugs into the existing factory harness and the OEM-1. Then use the AMP-RCA from list "B". As above it plugs into the OEM-1 and has 4 channels of RCA output and an amplifier trigger lead.

Connect up the additional amplifier as above, adjust the OEM-1 and the installation is complete.

Jump to current list of cables available from PAC. Note: cables change as factory harnesses change and as aftermarket head units change. In addition, new models are added to cover every eventuality.

Where a particular cable is not available, we have a universal cable, the RAD-UNV, (it requires wiring connections) for adding a head unit and/or an amplifier and a universal cable for adding a pre-amp RCA output head unit, the RAD-RCA.

 
DON'T WIRE IT AND PRAY . . . PLUG IT AND PLAY!
