i love these kind of jobs
raytech.... fix all those identified problem areas and then get back to us
Hopefully the truck will return back to normal operation once the sensors and connector issues are repaired.

Honestly i'm really surprised the truck ran at all with all these things wrong with it. Going to be a costly repair job for the customer but then again maybe he should be notified that untrained people working on these machines is what causes these kind of problems in the first place. Also that this system was put on there for a reason and from a legal standpoint should not be tampered with by unqualified untrained personnel. It would be a great way to convince the customer to give you his business once you get the truck back running good again. Just a thought ;o)

Good Luck
