Priority number one is finding a location for the convenience module and its attached fuse block. It's not terribly large at about 4x6 inches, but this Mustang had several additional upgrades like power windows, alarm, A/C, and more, that produced a bit of a head scratcher. We finally decided to mount the module on the side of the A/C evaporator case. The kit comes with Velcro strips, tie-wraps, and tapping screws for mounting the module. We chose the Velcro strips and they worked perfectly.
