I am really wanting to get a remote start put in my vehicle. I called a few places around town and they are all charging around $240.00 for install+product. My question is, I could get a nicer unit for that price and install it myself, but how hard is it to do? I have a wiring diagram for my truck, I just don't know how much involved these systems can be. I don't think I'll do an alarm, just the remote start.
