Different people use different ways to tap the wires. DONT USE THE CLIP ON THINGS!!!! Buy a pair of center-strips, mine were like $11 at VIP. Then wrap your remote start wires around it, and then solder. After that, wrap in elec. tape, and pull on the elec tape when you do it, it makes it stick and hold better, it wont come undone (little trick if you didnt know). Make sure you do it right, being stuck somewhere in the cold, trying to figure out what came undone sucks (not that I've done that). I'm not sure why installers get such a bad rep, I know I did everything right, and if I didint know I went right to the boss and asked, or had him do it. But then again I hated to have to fix other shops mistakes, and I had a few (Best Buy and those places).
