Application && Compatibility

The Metra 70-1120 is a factory amplifier bypass harness designed for Volvo 240 Series models from 1990 to 1993 and Volvo 940 models from 1991 to 1995. It plugs directly into the vehicle's radio harness to simplify aftermarket stereo installation.

Installer Fit

This harness suits installers replacing the original radio in the listed Volvo models while retaining the factory amplifier. It is not for vehicles outside the specified model years, for systems without a factory amplifier, or for buyers who need a standard power-only adapter without the amp bypass function.

Connection Reliability

The harness provides one 14-pin power plug with 7" of wire and one 14-pin amplifier plug with 60" of wire for routing flexibility. Under sustained use the fixed-pin connectors maintain a stable electrical path between the aftermarket head unit and the vehicle's factory wiring and amplifier.

Questions about this item

Do I need a separate aftermarket stereo to use the 14-pin harness?

Yes, the harness plugs into the factory wiring at the radio location so you can connect an aftermarket head unit without cutting the original loom.

Will the 14-pin amp plug with 60" of wire reach the factory amplifier in a 1991 Volvo 940?

The 60-inch lead is designed to span the distance to the factory amp location in the listed Volvo models, allowing a clean bypass without extensions.

How can I confirm the bypass is working after installation?

With the new stereo powered on, audio should play through all speakers at normal volume and no warning lights should appear on the instrument cluster.
