Looking for a wiring diagram to do a remote start and alarm on a 2005 Scion XB
(my apologies if this is a repost....i obviously don't know how to use search - but I tried!

thanks

 

look in the tech section. It shows the basic wiring for an alarm. As long as you have some basic electrical skills then it should be no problem. I just put an alarm in my 06 xb and it only took a couple of hours.
BTW google search of a site is better; ie "what you want to search" site:www.scionlife.com

 

audiovox has a very helpfull section on their website with wiring schematics for almost every vehicle you can think of. It's a lot like directech's website, except this one is FREE and anyone can sign up. You don't have to be a dealer. Here's the link: http://techservices.audiovox.com/Login.aspx

The12volt.com webiste is also a good reference for finding owner's/installation manuals for lot's of different alarm systems. Again, you have to sign up for an account but it's free as well.
