Well you didn't specify what you needed help with so here's a list of what I have done for minnesota weather.
1. get oil change with synthetic oil. They stay fluid down to buku below zero.
2. flush radiator if you haven't done so in two years.
3. Get engine block heater. Some attach to the radiator hose others attach to the oil pan.
Either one will do.
4. If they salt the roads up there, put a good coat of wax on the car.
5. If you have air suspension ride on the car, try to put some antifreeze in it. I know they make specific anti freeze for air brake systems, and I'm guessing the air suspensions could suffer the same fate. I honestly don't know if air suspension antifreeze is made cause I got regular shocks on my car, I'm guessing on this one.
6. Winter tires DO MAKE A DIFFERENCE! Not on ice though, you still slide but just not as far.
But even with winter tires, sand bags (100lbs.) and a full tank of gas, a mustang will have trouble starting from a dead stop. Well at least my 95 does. In up to 6 in of snow I can personally attest to awesomeness of winter tires. As long as you don't drive like a moron the tires will get you where you want to go. 7.If local laws allow studded tires, defiantly score you a set.

8. Don't make the mistake of buying only tires for the back. If you do, you turn your mustang into a snowmobile/and available traction is cut in half, so don't go cheap.
9. If you have the option you should score a remote starter. It gives you a nice warm car to walk to and you don't have t worry about scraping your windshield anymore. Just leave the heater set on defrost when you go in for the night. In the morning, remote star and you get a warm car with clear windows. Granted you do have to let the car warm up first but with an engine block heater it's MUCH quicker.
10.Disreguard last statement if you have a garage. DO NOT disregard if it's a detached garage.
Well this is all I can think of. If anybody else wants too chime in feel free. I work at a ford dealership and will check on the whole traction control thing at post tommorrow.
