I got
this one from summit. I think I paid $109 for it a few months back. I dont know where to mount it or how to install it on a new stang. It was fairly easy on my 90gt, I mounted it on the dash to the right of the guage cluster, ran the wires through the speaker cover on the left, and hooked them up. One to the power, one to a fuse that is activated with the lights, one to ground, and one to my MSD box. Again, I wouldnt know how to hook it up on yours whereas the ignition system is different.
