METRA 70-1768 Ford Common Ground 5 Wire Amplifier Integration Harness 8 Pin car electronics accessory

Ford Common Ground Amplifier Integration

This Metra 70-1768 harness integrates an aftermarket radio into Ford vehicles equipped with common ground amplified systems using the football style amplifier. It connects directly to the factory wiring via two eight pin plugs without cutting any original wires. Four RCA plugs link the radio pre amp outputs to the factory amplifier. The accessory suits owners of 1986 to 1993 Ford Lincoln and Mercury models who want a clean installation.

Vehicles With JBL Or LUX Audio Systems

Buyers whose Ford Lincoln or Mercury vehicle uses a JBL or LUX factory audio system should look elsewhere because this harness is not designed for those configurations. It also does not suit vehicles outside the 1986 to 1993 model range or those without the common ground football style amplifier. Installers needing a solution for non amplified systems or different connector types will require a different adapter.

Five Wire Connection With RCA Pre Amp Outputs

The harness provides five wire integration through four RCA plugs that carry the aftermarket radio pre amp signals to the factory amplifier. This arrangement handles the common ground amplified system comfortably while preserving the original wiring integrity. It runs out of headroom when the vehicle uses a premium branded audio system or falls outside the specified Ford Lincoln Mercury model years because the connector pinout and signal architecture differ.
