I'm buying a new wrangler sport, but I'd like to skip out on the "s package" because I'll be lifting the wrangler 2.5" and getting 33" tires anyways. I'm wondering how hard it is to install aftermarket power windows and locks with keyless entry myself would be. Anyone do this before? I'm looking at buying the electric life power window kit and power lock with keyless entry kit from quadratec. Any other recommendations?
