if its locked up, autowatch did a decent unit - 457 RLI and the GPS unit to go with it. whoever does it needs to BURY both units. if the have the lower dash off only then it means the average joy rider will have it disabled in 30 sec. when I did these (search the forum for my name) it was a 2 day affair usually and I charged accordingly. dash completely out , unit buried and fully integrated into the harness and OE relays used for the disable points. even those were hidden well. I retired (not by choice) in early 2017 and do GPS telematics in the USA now for Verizon/Vodafone.
