***SOLVED*** There is a little black box at the bottom of the firewall, on the outside of the truck , drivers side ticked in behind the clutch linkage. Mine is actually facing down towards the ground under the firewall with the plug going up. This is called the RX Module and cost me $180cdn and 1 minute to change with 2 star screws holding it. Instantly I got my pyro, fuel gauge and all 3 diff temps back. Still no tranny temp but that's from a busted sensor so I'm 100% now! Thanks everyone for your help!
