should be a pretty easy install from looking at what b white posted. only one ignition and an accesory that makes life easy. most alarms if there is more than three you need an extra relay. and use the 556UW bypass it's one of the easies to use

 

the reason it is so high is becoause no body wants to install a used alarm. the dont know if it works before they install and then they have to a item that isnt the norm for them to install. So if you have ever worked on a car after someone else you know why they charge so much

 

exactly as above. When I installed I hated trying to piece together used junk. I could install one of the Python or Schoshe Systems We Sold in half the time.

 

I agree with the above, most places can do it for cheaper with a new product than an old one. My Viper alarm I had put in a while back has everything you're describing except for the remote start because I didn't want it and bran new installed after everything was said and done was $550. But in any case unless you're really good with wiring schematics and not electronically challenged when it comes down to wiring/soldering and all that fun stuff I'd either bite the bullet and sell the one you have now on ebay and buy a new one that will probably better than the one you have and "cheaper". Not to mention if they put in your old one there is no guarantee that it will even work afterwards and they cant guarantee it either, so you could potentially be out $500 with nothing to show for it.
