Ford Mustang CD Player - How To Install a Modern Stereo and CD Changer

4 The USA-5 wiring harness makes power and speaker hook-up easy. The leads for ignition (red), ground (black), and battery (orange, for constant power to maintain program memory) pass through a filter box with fuses. Speaker leads are provided for front and rear speakers.

5 Crimp-on connectors are not included, so have a supply for easy connections to factory wiring.

6 With the old radio removed, the USA-5 slips in from behind the instrument panel. On a non-A/C '65-'66, this is about as easy as it gets. However, with A/C, you may need to unbolt the underdash evaporator so it can be moved forward for better access.

7 The head unit is secured to the instrument panel with shaft nuts, which will be hidden by the factory-appearing knobs. A mounting strap is also supplied to support the rear of the radio to an underdash bolt or screw. Now we can plug in the main wiring harness and antenna lead.

8 Moving to the trunk for the CD changer installation, assemble the mounting brackets using the provided bolts and nuts.

9 Then attach the brackets to the CD changer. Depending on how the brackets are mounted, the CD changer can be positioned at 0-, 45-, and 90-degree angles.

10 To mount the CD changer to the sheetmetal behind and above the gas tank on our '66 convertible, Merv assembled the brackets at the 45-degree angle. There are a variety of ways to install the CD changer, but Merv felt this installation was best for a convertible.

11 With the CD changer in position, mark the sheetmetal in preparation to drill holes for the bracket screws.

12 Before drilling, make sure there's nothing behind the sheetmetal that could be damaged. With our installation in the '66 convertible, we had to confirm that there was no interference with the fuel line or fuel-gauge sending-unit wiring.
