actually edward, cat does have a service bulletin out listing all the plugs, pins etc for all the plugs on these trucks. I remember running across this list in a tele-conference bulletin.
Unfortunatly i did not save it.

And yes depending on what year the truck was built, they went to a 2yr std warranty right after Tier2 came out or maybe when Tier 2 came out.

If anyone wanted to know what the warranty status is on thier machine just call the dealer in your area, THEY can get the information from MCFA.
