Install for 50$ that rocks, I know no one where I live so I had to DIY, or get *****. I went to a shop that wanted 600$ for a viper 790xv(?) w/ RS installed in a 96 yukon. 100$ each for 530t window modules and 50$ per window to put them in. Thats like 1000$ for all that if they don't try to get me to get anything else. :thumbsdow I went ahead and bought 2 530t's and a 560xv for 280$ and installed it all myself. I know only a little about the electronis part, but I used to dismantle cars for LEA's for 4 years. It was hard, but not impossible. The only thing I still can't get exactly right is the **** Remote Start, but I'm willing to have everything else work perfectly, wires hidden, everything soldered, and I know where everything is.
From my experience, the only really "hard" part is knowing where all the wires are. Make sure you have a volt/ohm meter and TIME (like 2-3 full days). The inexperience will make you take 3-4 times as long as a decent installer at least. It all depends on how strapped you are for cash and if your willing to bust your *** and learn. I think the install would've been worth 200$ for all that, but not 700-800 like they wanted. Shop around, or read up, either way you have to live with what you do but no guts, no glory.
