Features

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.

Harness Location: The factory plug that mates with the Power Harness is located in the factory radio cavity of the vehicle. The factory plug that mates with the Speaker Harness (used to bypass factory amp) is located at the external factory amp location (in rear of vehicle). The 17' speaker harness will need to be plugged into the output harness of the external factory amp and then run up to your in-dash aftermarket head unit for speaker wire connection.

Note: An external aftermarket amplifier is recommended to connect the factory subwoofer channels (if present) of the wiring harness in order to power your vehicle's factory subs.

I am trying to install an OEM Factory radio (touchscreen version) from a 14 Scion FRS into my 04 celica GT with JBL amp system. Will this bypass work for the other OEM radio?
