If I remember correctly, each procal is only to be used on one vehicle. You have to restore the first vehicle to factory specs before using the procal on a second vehicle. I don't know if any local shops have a "master" one that can be used on unlimited vehicles or if you have to purchase your own. I think they retail for around $160ish.
I don't live in Yuma so I cannot help, but if my info is correct it may save you some time waiting for someone to respond.
EDIT: here's the link, the question is the 12th one down. LINK!
EDIT #2: here's the link to Quadratec's site. Someone may be able to point out a cheaper site to buy it at, but at least here's a start for you. AEV Procal LINK
