About the Metra 70-1770 Receiver Wire Harness

Metra 70-1770

This vehicle-specific wiring harness makes connections between your new car stereo and your car's electrical system.

Metra 70-1770

This vehicle-specific wiring harness makes connections between your new car stereo and your car's electrical system.

First, attach the color-coded wires on your harness to the wires from your new stereo. If you don't know how to use a soldering iron, we recommend that you purchase some wire connectors that you'll use to attach this harness to your factory harness.

Now, once this harness is connected to your new stereo, you'll be able to plug right into your car's factory radio connector. This harness makes installing your new stereo easier, and allows you to put the factory radio back when you sell your vehicle or return it at the end of the lease. Warranty: 60 days.

Please read this important note: This harness may not contain provisions for every wire needed to complete your installation, and it will not accommodate special navigation, video, or factory steering wheel control connections. You will need a special adapter if you want your factory steering wheel audio controls to work with your new stereo.

Product Research


Wiring Harness: This 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 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 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 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.

Greetings Gary, and thank you for your question. That model harness production date before 2013 had an orange/black, and a black/white wire. Both were not used. Post 2013 that same model harness had the orange/black, and the black/white wires removed. Tape them off, and dont use them.

My '97 F150 Lariat Premium OEM stereo has a 6 disc changer, and 4 speakers with a 16 pin wire harness and the 5 pin harness (grey above). I cannot find a kit that has both wire harness' together in a kit. Any suggestions?

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle to see if we have something that will integrate, and any other options available.

My radio dont have the orange cord to connect to. Does that matter?
kaiden  Jun 08, 2021

Orange is the dimmer/illumination. If this doesn't matter to you,, then you will be fine to run your headunit. Sometimes, the orange wire may be a different color, just depends. Make sure to look for the dimmer/illumination wire.

I do not have a car with Mach 460 but this unit has a fairly conventional wiring interface and there appear to be specific pre configured interface cables available. There are also some very detailed installation instructions from several sources. The most comprehensive that I found are located on the ModdedMustangs website.
