You're better off having a dealer install the remote starter for you. My dad tried to install one in our old '05 Grand Am, but it was a pain in the butt to get it to even turn the lights on. (Just one of many,
many reasons we dumped that car...

)

No kidding. My car ('99 Saturn SL) obviously had the dash apart at once point; there are missing clips and screws in various places. The center console area was really messed up; almost every clip was broken and half the fasteners were gone. (Between the previous owners getting it in an accident and not installing the aftermarket radio properly...

Luckily they used a wire adapter, instead of cutting the original connector off the dash harness.) Last year I got fed up and rebuilt most of the missing support bits, secured the radio (it was sitting loose with just a couple folded metal tabs keeping it in place

), and now it doesn't rattle nearly as much as it used to!
Stark contrast to the old 1974 D200 pickup we have kicking around. It's got the slant-6 engine designed in the 50s, 1-barrel carb, manual transmission, straight exhaust, and no options (aside from an aftermarket AM/FM stereo cassette player and power steering). You could probably take that whole truck apart with a philips-head screwdriver if you wanted to.
