Thanks for the input. If you don't mind, I would like to know what book
that 
info came from and where to get it. I have a haynes manuel that claims to 
cover (1993 thru 2004) but I have found it lacking a lot of info about my 
2002 max including any info at all about the vias system. I would love to 
have a book that covers everything.
