METRA 70-5521 2003 & Up Ford(R) Amp Integration/Sub Harness

El arnes quedó a la perfección, muchas gracias solo que al querer conectar el arnes chico mi camioneta ya no trae el conector macho que es para el subwoofer de fabrica que trae la camioneta la cual es una explorer eddie bauwer 2005.

This just arrived after waiting patiently for its arrival from the USA. Unfortunately this does not fit the Ford Explorer 05 as stated. Good quality item, but clearly a waste of time and money as seller is USA based, this isn't worth a return!

Metra 70-5521 Crutchfield claims this kit does not exist or work on my 07 Mustang with the Shaker 500, and insisted I purchase an expensive PAC kit that requires soldering a diode. With the 70-5521, there are 2 harnesses. The large one is for the main radio harness, the smaller one is for the Shaker 500 subwoofers. You will need a LM7805 or equivalent voltage regulator to convert a 10-15 V signal into a 5V signal. The LM7805CT voltage regulator was needed because the Ford factory Shaker 500 amplifiers require a 5V turn-on signal, while aftermarket receivers use 12V turn-on signals for the amps. This results in a pop or overload of the amp turn-on. The LM7805CT seems to do the trick, and I was told by other Mustang owners not to worry about heatsinks or cooling the regulator because the current/power dissipation isn't that great. I also observed that it was definitely possible to tap into the light/illumination leads for either the message center harness or the HVAC harness to enable the dimming feature on the CX501, but I opted not to touch the factory wiring. The main factory harness does NOT have a power antenna (solid blue), amp turn-on (blue/white) or phone mute (brown) so those must be sealed/wrapped off on the big Metra harness. The smaller Metra harness that goes to the Shaker 500 will have a pair of amp turn-on leads (blue/white) that attach to the OUTPUT side of the LM7805. The INPUT side of the LM7805 goes to the amp turn-on lead coming from the receiver harness. The RCA inputs for the Shaker 500 subs go to the appropriate RCA jacks on the back of the receiver. I soldered all of the ground leads together which goes back to the receiver harness ground lead. I used solder and heatshrink wrapping and can confirm that this wiring kit will work on a 05-09 Mustang (or at least the 2007). Overall: 5/5 stars, very inexpensive, not hard to use, just remember to buy a 5V regulator from Radio Shack - I opted to buy my Fairchild LM7805CT from Digi Key so that I knew I was getting a quality regulator.

Fits Perfectly and works as it should, good plug ... Fits Perfectly and works as it should, good plug ... Fits Perfectly and works as it should, good plug ...

I purchased this to install a 7" flat screen in a 2007 Ford Mustang GT. All the wires are there. Simple plug and play operation. Good price, shipped quickly. Would recommend.
