alright so back in october i got a Viper alarm and autostart for my birthday and it sat all winter not being installed, which would have really helped me on some cold days, anyways, i went to a local shop and asked how much to install it and they said it would be $50 for a bypass and $400 to install it!?! that sounds ridiculous.

so my questions to you guys would be
do i really need a bypass?
if so, which one would be good?

and i dont believe its truly that hard to install, so are there any threads or wiring diagrams? i couldnt find much when i looked back in october

thanks for the help!

my car is a base 2005 grand prix
the alarm/starter is a Viper 5704V
