I finally got around to my gauge install. Got a copy of "Got Gauges" and started. Gauge pod was drilled in the wrong spot for the speaker and Autometer is working on the problem. Ran the boost line and tapped the light wiring to the INTPARK fuse in the engine compartment. None of the wiring is hooked up because the pod doesn't fit. Anyway after restarting the truck the SES light was on so I downloaded the faults:U2106 Throttle Actuator. Cleared fault,keeps coming back. Rechecked all wiring etc. no joy. Then also noticed that there is no underscore under the PRND21L indicator and it goes into gear with a horrific clunk. Removed The Juice, cleared code still no good. Any of you great wizards have any ideas? By the way truck is a 2003 C3500
