"I used the Metra 70-1761 wiring harness for my 2013 Toyota Yaris L and it was a perfect fit. The installation process was a breeze and made connecting my new radio quick and simple. The harness feels solid and durable, and it really saved me a lot of time compared to splicing wires or modifying the factory setup. It's a reliable, essential accessory for a stereo upgrade—absolutely recommend for a seamless install."

"When I upgraded the original stereo in my 2004 Sienna with a new unit, I initially struggled with the connectors. After some research, I learned to connect the Metra 70-1761 to the 10-pin and 6-pin connectors at the amplifier instead of the ones behind the head unit. Once I did that, it worked perfectly. The only drawback was the lack of clear instructions, which cost me time, but the harness itself is affordable and effective."

"For my 2001 Toyota Camry, the Metra harness made the install process much easier.

"When I used this harness to install a new head unit in my Acura, all the wires were pre-cut and easy to strip, and the packaging included a clear wiring guide. I liked that I could do all the wiring at my workbench and just plug it in once I was in the car. While you could technically do the install without this harness, it made the job faster and safer. Just note, if you have a factory subwoofer, you'll need to wire that separately."

"I used this harness for my Honda CR-V, and it fit perfectly with my Kenwood stereo. The instructions were detailed and accurate, and all the wires matched the original harness. Wiring everything up was actually kind of fun, and I haven't had any issues since the install. My only minor gripe is that it didn't come with crimp connectors, but that's easy to work around."

No cutting or splicing required, and the whole process was fast and straightforward. Highly recommend this for anyone looking for a professional, hassle-free speaker install."

"When I replaced my Silverado's door speakers, this harness made the job quick and efficient. I just had to disconnect the old speakers and plug these in—it matched the original connectors exactly.

"I used this harness for my 2003 Avalanche, and it worked out great. No need for unnecessary rewiring, plus it’s a great alternative if you want a clean, factory look. The only minor challenge was that it was a bit tough to attach at first, but overall, it made my speaker upgrade very simple."

"After trying a cheaper adapter that wouldn’t power my radio, I got this for my 2003 GMC Sierra. The wire colors matched perfectly, and everything worked as expected. My truck doesn’t have steering wheel controls, so I didn’t need those wires. This adapter made the install smooth and fixed my power issue."

"Installed this in my 2005 Trailblazer and it worked flawlessly. I didn’t need OnStar, so this was a great fit. Chimes are retained, although a bit quieter, and installation was straightforward.

"I installed the Red Wolf harness on my 2002 Chevrolet Impala base, and it worked just as expected. I did need to use the extra red wire and create an accessory wire for the deck to power off with the key, but overall, it’s one of the few harnesses that actually fits."

"The harness fit my aftermarket stereo and factory plug without any cutting. All the speaker and power wires lined up. Just be aware that the factory wiring doesn’t have a 12v accessory wire, so beginners might find this a bit tricky. Instructions weren’t great, but with a little research, it works well in the end."

Everything matched up perfectly and I had my new head unit working in no time. Great value and very user-friendly!"

"I installed this in my 2002 Toyota Camry XLE with the JBL audio and it’s been working flawlessly for months. Both power and audio run without any issues, though the fit in the dash was a bit tight, but that’s pretty typical for these kinds of installs."

"When I put this in my Avalon 2002 XLS, I had trouble getting sound at first even though the radio powered on. After some help, I realized I needed to splice the blue/white stripe wire with the blue wires for it to work. I wish the instructions had been a bit more detailed, but once I got it set up, it worked as expected."
