05 Expedition XLS

[thatnigga]

Ok like the title says I have a XLS 05 expedition right now I'm wanting to do a few upgrades to it and don't know if it's possible. Please help me out if you can, thank you.

1) I want to change the factory radio, is there any problems in doing this (i.e. will something else stop working if factory radio is not installed)?

2) The car has a factory alarm, I'm assuming as I use a factory key FOB to activate it. When I click the lock button it beeps three times realy loud, and when I unlock it I get the same thing. Is this normal? Is there anyway to change this? Also it is very sensitive and with kids it goes off whenever they even approach the car, so is there anyway to change the sensitivity?

3) I want to add fog lamps to the vehicle and don't know if this is possible? I see wiring near where the fog lamps would go in on both sides. Is that for the fog lamps? How would I go about turning them on and off if I installed them using this area.

4) Are the running boards on this car supposed to be lighted?

5) I'm about to get some new rims for the car and need to know what the wheel sizes and lug patterns that will fit my car. For instance will 22's fit 20's.

Your help and quick answers are appreciated.
