Great for DYI

made hooking the radio up a lot easier for someone who was doing it for the first time

easy

Worked like a charm. Wires all matched up as they should

Perfect match

This wiring harness made installation easy. This was my first stereo installation and I had only 1 wiring issue because of the instructions included. There was an issue with the power antenna wire, but I think the issue was with the original wire. Do not cut wire until you are sure of wiring installation.

makes things easy

great for that "no hack" installation.

Must have when replacing stereo

You need a wire harness to make your stereo swap as easy as possible, and this unit makes that possible.

Great buy!

I ordered and installed this wiring harness in my 01 Mazda Tribute six months ago and have never had any problems with it. It took less that 5 minutes to install

Not too bad, but theres better wire harnesses out there

Not too bad, better than nothing. I used this on a 1990 Mazda Rx-7 convertible. It may work good for other cars, but on my car it was wrong. The remote on for the factory amps was on the wrong plug. It is suppose to be on the larger plug at pin 10 (Brown/Red wire from the car). Where the remote wire was it went to 12V constant (blue/white) from the car. This kept my radio powered up all the time. I'm glad Pioneer has the remote trigger monitored and diode isolated from stupidity like that or I'd been getting a new radio. Also one of the crimp terminals was bent a little, when plugged the connector in, it tried to bend the pin. Just look out for that. I'm a old veteran car stereo installer with 14 years experience, and this is one of the worst connectors I have seen. Just remember to specify you'd like a Metra wire harness, you'll probally be happier. :)

No Ground?

This wiring harness worked good, except there is no ground wire on the plug. Ground wire is its own free wire in the radio slot. Used in a 1993 Miata.

Good Product

Did exactly what I needed, well made harness and an easy install.

It is an accurate adapter

I was able to use the adapter in my 2000 Mazda 626 and all the wires matched up. Used this adapter to go from stock Mazda head unit and cassette player to Sony MEX-BT5700U

Great product, a must for installation

Wiring adapters let you wire up your radio on a bench, then when it is time to install it in the car you don't have to splice any wires. Also, if you sell the vehicle you can just plug the original radio back in because the original wiring will be intact.

Plug and Play

Easy to use and wire matched factory plug wiring harness

Scosche MA02B

The MA02B is not the right adapter for my car. I had to purchase a MA03B to install the radio in my 2006 Miata w/o the bose stereo.

Terrific value

This harness was a game changer, it made installation of my radio a breeze. I would recommend this to anyone looking for a good value.

Good item!

Fairly priced, just what I needed!
