Metra AX-TOY28SWC Steering Wheel Control Harness

Metra's AX-TOY28SWC harness allows you to connect the steering wheel audio controls in 2012-up Toyota vehicles (if equipped) to a new car stereo without having to splice into your factory wiring. It's compatible with the 28-pin Toyota wiring connector that detaches from the factory radio.

To use this harness, you'll need the Axxess ASWC-1 steering wheel control interface (sold separately) and a compatible aftermarket radio. 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 (if equipped). This adapter will work with select 2012-up Toyota vehicles equipped with steering wheel audio controls. Warranty: 1 year.

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.

So easy!

Crutchfield Customer Review (What's this?)

This harness makes installing your new ASWC-1 Sterring wheel control adapter module a painless process. No splicing, crimping or soldering. Simply plug the 28 pin connector in, plug in the RCAS to the head unit along with the 3.5 mm jack, and plug in the harness to the ASWC-1. Discard the harness that came with the ASWC-1. This is totally worth the price.

Pros: simplicity not to long of wiring

Cons: none

2015 Toyota Camry
Crutchfield Customer Review (What's this?)

Used this harness in combination with the Axxess ASWC-1 to retain the steering wheel controls on my 15' Camry when installing a Pioneer AVH-4700BS. I didn't to cut into my OEM steering wheel harness that this directly connected into it & thus I used the ends of this wires to tap into the harness coming from the back of my Pioneer. I took off 1 star because the RCA auxiliary cable of this harness was very noisy and as my Pioneer had a 3.5mm aux port (as most head units have), I had to the a male 3.5mm to female RCA adapter only to find out that the RCA was noisy. I confirmed my head unit didn't have a faulty aux port as I connected my iPhone 6 directly to it & my music played flawlessly. Ended wiring a AUX + USB harness I got off Amazon to the back of the Pioneer. Looked clean after I was done.

Pros: - helped retain the steering wheel controls - didn't have to cut into the OEM harness - easy instructions - direct fit into the ASWC-1 module

Cons: - the RCA aux cables were very noisy & didn't work

Worth it

Crutchfield Customer Review (What's this?)

FYI - installed it into a '13 tacoma. Makes it much easier - takes the place of the harness that comes with the controller- snaps into the Toyota harness, connect power (red) and ground wires, plug into the controller, and connect remote plug to head unit-- done. This takes the place of the connector that comes with the steering wheel controller --- the black plug goes into the controller "box" --- you do not use most of the ones that come with the aswc controller. Also has RCA l/r plugs to connect the dash audio input to the new head unit ( if your new one has an input, mine didn't -- but if yours does, that's what they are for).

Pros: Easy , once you figure out what goes where- instructions don't mention this adapter so it looks like there's a lot more wires to connect than there are.

Cons: Instructions on axxess website for vehicle don't mention this adapter even though it's their part.
