Great Buy!

This connector was exactly what was needed. Very easy to connect to the existing wiring. Installation took minutes.

Versa 2010-1

Don't use this until you check out the many websites about using this product. It isn't self explanatory. As for the antenna plug, use a RCA jack/plus.

A must have

You need this. It makes your install 1000 times easier. If you have ever tried to install a head unit without one you know what I mean. The wire colors matched up perfectly with my head unit.

Does not fit description

This product is supposed to work with a factory Bose sound system but it does not. You either need
special adapters for the factory amps or go with the PAC harness.

Perfect.

Another great product from Scosche. Makes for a nice clean install. Used to install an Alpine IXA-W404 into my '09 Nissan Titan. No issues whatsoever.

did not fit

This was sent with my new stereo and supposed to fit my 2011 Nissan Frontier, but did not. I just spliced the stereo wiring into the factory wiring.

Buy

It's the right product for Versa install.
Not cutting OE connector and having the ability for custom mods.
Solder and heat shrink wires in harness.
Do not twist and/or crimp then tape.
Value OK at full price.

Perfect Connection

I installed this with the Pioneer Premier FH-P800BT in my 2008 Subaru Impreza 2.5i, and it was a flawless install. No complaints here. The wire gauge matched right up with that of my car and new head unit.

It works, but expected more

I routinely use this company to install my dash units but I found that this doesn't have the radio antenna adapter and I lost functionality of the driver information display in my car (07 Sentra See Spec V and things like mpg, temp and distance till empty). If it weren't for the fact that I hated the factory head unit so much I would return it since it only wires the stereo but not much else.

Mandatory for a good clean install

Never cut factory wiring, these are the only way to go for a good, solid, and clean install. I would recommend soldering and heat shrinking connections. Especially for mic or swc connections. I used butt connectors and tape initially and had nothing but problems. After solder and heat shrink it was solid. Trim a few inches off stereo and this harness leaves more room for RCA cables. The directions were, short and and accurate for wire color and function.

Worked great on 09 Subaru

This fit my 2009 Subaru wrx. I was skeptical seeing how it said Nissan on the package. You just have to flip the connector, what appears to be upside down, and it fits perfect.

Great product

I needed this to identify factory wiring for the door speakers in my subaru wrx via the factory harness. All the diagrams I was looking up online gave me conflicting info. This helped tremendously. Even though I didn't need this to utilize for my install, it was a great helping tool to complete my wiring.
