SCOSCHE 2000-05 Ford Premium Sound & MACH Audio; Power/Speaker and RCA to Sub Amp input wire harness

Proper adapter for 2003 Ford Expedition with Premium Sound System (Amp and Sub). Amazon stated that the FDK 11B was the proper adapter and that the FDK 13B would not fit my car. In both cases they are incorrect, 13B is the proper adapter. Scosche provides amazing customer service!

Chances are you are buying this to install an aftermarket headunit in an explorer or mustang right? This is the harness needed when you still want to utilize your stock amps with the mach 460, or 1000 premium stereo system. I used this in my 2003 mustang and it fit perfectly. This was easy to use, and I recommend this over Metra as well.

This harness worked great for my buddies 2002 Ford Mustang GT. It was a little difficult to figure out at first, but it came out good. The car sounds awesome, everything works on the new radio, and hes happy.

If you have a mustang with the Mach 460 this is not the right harness. The Mach system has two sets of RCA plugs, this harness only comes with one set. Also, the mustang plug is a 6 pin and this harness is an 8 pin. You want to order the metra 70-5510.

Used this in my old car for my new radio and it was perfect.

i got this product to upgrade my audio system in my car i got my amp to work with original wiring helped making a after market amp a breeze

Bought this for my 01 mustang with the mach 460 factory system. The main harness (bigger Plug) worked fine. The one for the amps (smaller plug) didn't just plug in, I had to do some modifications to get it to work. It works but beware you might have to modify the amp plug. I'm an ASE certified technician.

Harness works great. I think better instructions would be a plus for the more advanced system.
