Worked Great, no Issues, colors weren't exactly the same as new headunit. Did some research online until I was comfortable connecting them all with waterproof butt splice crimp connectors. Worked great.

Works as intended for a 2004 f150. Came pre spliced and ready for install. All wires are labeled as well which is a plus

I just used this wiring harness yesterday to install an aftermarket stereo on my 2006 Hyundai Sonata and I want to point out a couple of things. As others have pointed out in their reviews of this wiring harness, as it relates to the 2006 Hyundai Sonata, this harness is missing a couple of wires. It also actually has a couple of extra wires too, that won't end up being connected to anything in the factory stereo wiring harness, but those can be just capped off and ignored. But what's more concerning for those of us with a 2006 Hyundai Sonata is that it's missing a larger spade connection at factory harness location 24 for the power antenna, and also a smaller wire connection at factory harness location 19, which is the remote control ground (required if you want to have your steering wheel radio controls work on your new, aftermarket stereo). As "jasper pipestone" points out in his review, a large wire is missing for the power antenna. He mistakenly refers to this as factory wiring harness location 13 in his review, but it's actually factory wiring harness location 24. Factory Harness location 13 is the black (common ground), so don't remove that one!. You actually want to match up with the funky green colored wire on the factory wiring harness for the power antenna line, which is at factory harness location 24, on the opposite side from the big black and gray wires (black == common ground and grey == battery/constant power). I did what he suggested and bought an extra wiring harness because I knew I'd be short a couple of wires, and these wiring harnesses are cheap. I popped the red wire retainer out from both harnesses. Then I lifted the little plastic clip on the inside of the wiring harness that holds down one of the bigger spade wires and removed it from one harness and then put it into the other harness, solving the location 24 problem. Also, this harness does not have a wire that matches up with factory harness location 19, which is the remote control ground, which is required if you plan on hooking your after market stereo up to a steering wheel control interface like the Axxess ASWC that I used. To solve this problem, I removed another (smaller) wire from my second/spare harness and put it into location 19 in the wiring harness I used to install my aftermarket stereo. Then I reinstalled both of the red wiring harness retaining clips. It works perfectly! I've uploaded a REALLY helpful wiring diagram for the 2006 Hyundai Sonata car stereo factory wiring harness here: [...] After adding the two missing wires to this wiring harness, I was able to connect all of my factory wiring harness wires to my aftermarket stereo with little problem. Hope this helps somebody else out there. =:)
