JONATHAN MACDONALD: It's no secret that '79 to '93 Fox Mustangs had a crappy ignition switch right out of the factory. Ford even had to do a complete recall on them.

What happens is the four crimp connections, where the metal body meets the plastic connector, weaken over time and allow the whole switch to fall apart. This means your car won't start, or it could stop running on you in the middle of traffic. Depending on your year model, accessing your steering column to get to the switch is going to be a little bit different.

Regardless, it's just going to be a couple of screws and a couple of plastic pieces to get out of the way, and you'll have the switch right there in front of you. You'll want to have a tamper-proof Torx bit set that has a T27-bit. You can find those on

Remove the two retaining screws, slide the old switch off the column, unplug the electrical connector, grab your new switch, line it up with the rod on the steering column, tighten down your two retaining screws, plug the electrical connector back in, and reassemble your steering column. And it's as simple as that. Our 5.0 Resto brand ignition switch is a heavier duty, and it's not going to fail like the original. And you can pick yours up at
