Overview

Our take on the Metra 70-8114 Steering Wheel Control Harness

Metra's 70-8114 harness allows you to connect the steering wheel audio controls in 2003-up Toyota-built vehicles (if equipped) to a new car stereo without having to splice into your factory wiring.

Metra 70-8114 Steering Wheel Control Harness

Metra's 70-8114 harness allows you to connect the steering wheel audio controls in 2003-up Toyota-built vehicles (if equipped) to a new car stereo without having to splice into your factory wiring.

To use this harness, you'll need the Axxess ASWC-1 steering wheel control interface (sold separately) and a compatible aftermarket radio (won't work with Parrot, Rosen, or Car Show radios). You'll also need a vehicle-specific wiring harness to install your aftermarket stereo. We'll show you the correct harness when you enter your vehicle information into our online vehicle selector.

Once you've connected this harness to your new receiver's rear RCA auxiliary input, you'll also be able to use the handy auxiliary input in your Toyota. This adapter will work with any 2003-up Toyota, Lexus, and Scion vehicle equipped with steering wheel audio controls. Warranty: 60 days.

Important note: The aftermarket radio you install must have a rear RCA auxiliary input if you wish to retain your factory auxiliary input.

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.

This was in addition to the other wiring harness needed to operate my Toyota Camry to my new radio. The RCA's are not needed and just hang but overall I am happy I have steering wheel controls.

Features

SWC Add-on Harness for Toyota/Lexus/Scion: When installing an aftermarket radio in  your 2003-up Toyota, Lexus, or Scion vehicle, the Metra 70-8114 harness allows you to retain your factory installed steering wheel controls without having to splice into your vehicle's factory wiring (120ASWC1, required & sold separately). In addition, the 70-8114 harness includes stereo male RCA connectors to allow you to retain your factory installed 3.5mm jack (your aftermarket radio must also have a rear-panel stereo Aux input).

Note: This is an optional harness; a main power and speaker harness is still required and sold separately. Please visit the Crutchfield Car Selector for your specific type of vehicle.

Thanks for your question. Looking at both harnesses you should be covered to get something in the 14 to 18 gauge range. Hope this helps. [ Kenny  Jan 20, 2017 ]  Staff
