Worked Perfectly
This part worked perfectly. We were installing an aftermarket stereo and didn't want to cut and splice the stock wiring harness. Plus it was challenging to figure out what colored wire connected to the new wiring harness. This cable resolved both issues. The color coding matched perfectly with the new stereo making splicing wires easy. Ultra quick shipping as well. High quality and great value.

Easy to Use, No Subwoofer Wiring for Acura TL
I recently used this wiring harness to install a JVC KW-XR810 head unit in my 2002 Acura TL S-Type. The wiring harness worked well and was easy to use. It was nice that all of the wires came pre-cut and ready to strip. The packaging also had a wiring guide on the back that explained what each wire's purpose was. This was helpful because all I had to do was match up the corresponding wires from the new head unit harness to the Metra harness. To be clear, you technically do not need to purchase this harness. This harness wires to the wiring harness for your aftermarket head unit and then plugs into your car's wiring harness. The benefits of this wiring harness are that you do not need to cut into your factory wiring and that you can do all of your wiring while you are seated comfortably at a table inside your house and then just connect the plugs in the car. So, while you don't need this to do the job, it is definitely worth the money for the convenience and for the reduced chance of failure. One thing I must point out is that this device is only wired to support 4 speakers (front L & R, rear L & R) so if your car has a factory subwoofer (i.e. a fifth speaker), this wiring harness will not support it. Also, I've looked around and there is not an aftermarket wiring harness out there that does support the subwoofer. Rather, what you have to do is run a RCA out of your new head unit and splice it into the subwoofer line for your car. There are plenty of "how-to's" floating around on the web. I was able to find one for my Acura TL and I have the factory subwoofer working now. Overall, I would recommend this. It works perfectly and is great for the price. -Cheers!

Super easy to install
This worked perfectly for the 2nd Gen Honda CR-V and mated to the Kenwood Excelon 696s Wiring harness does require assembly, and if you have auto wire strippers, USE them. Shrink tubing is what i used. I feel its better than butt-connectors. Every cable in the instructions they email to you matched up well to the OEM harness and I have not had any issues yet in over many years. Pros: It worked, lol it was kinda fun wiring everything, Perfect fit Instructions very complete and straightforward Cons: No crimp connectors included - it's okay. now I can do it with ease

Fit Honda Civic sedan 2000 perfect.
I purchased this wiring harness to install a replacement car stereo into of friend's 2000 Honda Civic sedan. The Metra comes in plastic bag with the insulation ends of each wire already pre-cut so you can slide the tips right off and be ready to make your connections. Wire gauge is quite good and the internal wiring is copper. There's a diagram on the bag that shows the Color correlation to function and that was very clear. The only confusion during the process was the dimming wire whose definition didn't seem to match up with the definition of the dimming function wire on the head unit harness, but I ended up just connecting them anyway and it worked properly to dim the head units display when you turn the car's headlights on. Overall this was Quality unit that fit right into the factory wiring and made the install go quick and smooth. I wish they included crimp connectors so you could just get right to connecting rather than make another trip to buy connectors.

Compatible with Accord 2002
The harness comes in a plastic package with a wire guide on the back. It is wired to the harness supplied with the radio, and provides a means to connect a new radio to the car's wiring system without making any splices. It was extremely easy to match up the appropriate wires on this harness with the wires comming from the connector provided with the radio. Based on color and using the guides that came with the radio and on the back of this harness package, it was very simple: for example: white to white, white w/black stripe to white w/black stripe, etc. Since my vehicle doesn't have a powered antenna or amplifier, there were a few wires that were left unconnected. My preferred method of connecting this harness to that which came with the radio was to strip both wires that needed to be connected together, slip some heat shrink tubing over one wire, twist the wires together, solder, and slip the tubing over the soldered connection, then to apply heat until the tubing shrinks down to the size of the insulation on the wires. The basic technique is shown here: [...] The result is an excellent mechanical and electrical connection.

Fits
It fits my Honda. However after ordering the infotainment center it came with a connector as well so I didn’t need this one hahaha

This harness and connector made installing an after market stereo a relatively painless project. I can’t imagine doing an install like this without a custom connector. So easy to take this connector and solder the wires to the appropriate wires on the wiring harness that came with the new stereo. Buy some good quality shrink wrap to do it properly and neatly. Fit my Acura RSX perfectly. The package has a description of each wire’s function so you can easily find the corresponding wire on the new stereo harness. Works perfectly.
