This fit my international Sure Sta.r When the dealership couldn't help me Crutchfield did. I just had to move 2 wires in the plug and I was good to go.

Pros: Fit perfectly

Cons: None

Easy as falling down stairs!

This, along with the guide from Crutchfield, made the radio swap completely painless. I had the harnesses joined together in less than 5 minutes, and that included time to go to the fridge for a beer. Swapped out radio in less than 5 minutes, and wiring was flawless.

Pros: Didn't have to chop wires off, colors on harness matched colors on head unit

Cons: Wasn't free, didn't add 2000 watts to this tiny man-beast of a car

Will make your installation much easier

I decided to change the factory head unit on my 2008 smart fortwo and to save me time and also to keep the installation as "clean" as possible I also got the adapter. Very helpful and handy. Even though there's a wire color reference on the back of the package, Metra also uses cables that are labeled themselves - which I found to be very useful when matching them to my HU's harness.

Pros: Wires are labeled themselves to help match head unit's harness; Well constructed;

Cons:

Wires in the wrong place - Don't splice - move

MeanDude from Greensboro, NC on 3/11/2016

2013 Smart fortwo

Verified customer (What's this?)
Verified employee purchase (What's this?)

2013 Fortwo - As others indicated, Metra messed up, or Smart changed something and no one told Metra. Either way, Metra should have been on it. Deal is that the switched lead needs to slide two spots to the left (as you look at the back of the harness) and the illumination lead needs to drop in between the switched lead and the ground. I called Crutchfield (great people) and I was told that I could insert a needle (sewing needle worked great) to the left of the pin (through the front/side that plugs in) and tug the wire to get it out. It worksd like a champ. Move the wire, snap it back in and you're good to go. Before buying into what I'm telling you, grab your tester or lamp and assure your car is wired like mine - and that they haven't fixed the setup since my post.

Pros: Typical color codes, plug seems to slide in and lock without issue.

Cons: The one I received had contacts in the wrong position for my 2013 Fortwo.

The switched power pin was in the wrong spot

ZachS from Maryland on 10/15/2015

2015 Smart fortwo

Verified customer (What's this?)
Verified employee purchase (What's this?)

Everything about the product was fine except that the switched power pin was in the wrong spot. I ended up having to go in with a multimeter track down the correct wire on the factory harness and splice in. The exact reasonreason why I used this was so I would have to cut up the factory harness.

Pros: Its 99% there

Cons: The one pin didn't line up with switched power

Metra 70-1783 Receiver Wiring Harness

Joseph from Austin, TX on 3/23/2010

This wiring harness worked great. It includes a wiring diagram and between that and the wiring info that came with my receiver I was able to easily figure out the wiring. I also cross checked the wiring online. Apparently different people wire the front and back in different ways in this car, but I wired the front speakers outputs to the factory tweeters that I left in the car. And I wired the rear speaker outputs to the door speakers (which I replaced). I left the factory underseat subwoofer in the car and left its wiring unchanged. This all seems to work okay for me. I can use the fader to adjust the tweeter level.

Pros:

Cons:

Could not ask for more

Jeff from Sycamore Alabama on 2/8/2010

Verified customer (What's this?)
Verified employee purchase (What's this?)

This piece fit the SMART harness great. The only thing i am going to have to modify is that the SMART does not have rear speakers and i am going to place some in the car, so I will have to come off the rear leads from the receiver and either make the connections directly or, more than likely, gonna get a connection and make another connection point.
