Metra 70-7002 Amp Bypass Harness

Metra's 70-7002 adapter lets you replace the factory radio in select Mitsubishi and Dodge vehicles. You can bypass the factory amplifier and use the more powerful amp that's built into your new car stereo.

Simply splice the color-coded wires on your integration adapter to the wires from your aftermarket stereo. If you're not using a soldering iron, we recommend that you purchase some wire connectors to secure the connections. Check out our handy article on three ways to connect the wiring harness here. Next, plug the Crutchfield integration adapter into the harness that you removed from your factory radio.

Since you didn't have to cut off your car's original radio connector, it's easier to put the factory radio back in when you sell your vehicle or return it at the end of the lease. Just plug the factory radio back in and keep the aftermarket stereo.

Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this adapter is compatible with your vehicle. Warranty: 1 year.

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.

Crutchfield Customer Review (What's this?)

Everything worked out fine. Made sure to score with a utility knife the pieces I had to remove. Even came with a bezel to trim up my head unit nicely.

Pros: Good fit.

Cons: None.

Product Research


Crutchfield Wiring Harness: Crutchfield wiring harnesses prevent you from having to cut your vehicle's factory radio plug when replacing your factory radio with an aftermarket head unit. Simply solder or crimp the Crutchfield wiring harness to your aftermarket head unit's harness (solder & crimps not included), plug the aftermarket head unit's plug into the rear chassis of the aftermarket head unit, and plug the Crutchfield wiring harness into your vehicle's factory radio plug.

Note: Installation tools, hardware, & accessories are not included & sold separately. Please see the Accessories tab for recommendations & availability.

Wiring Notes: If the Crutchfield wiring harness is not equipped with a ground wire, you will need to ground the aftermarket head unit's ground wire to the metal chassis of your vehicle. Some vehicle's may require you to bypass the vehicle's factory amplifier (in another location from factory radio) or hardwire certain connections. If your vehicle is equipped with factory steering wheel controls, an additional adapter is required & sold separately.
