Have Truck Repair Questions? Ask an Expert
Hi my name is ***** ***** for your question
Any problems with the way the engine runs?
Does check engine light ever come on?
If all okay, check the data link connections from ecm to cab,, and passthrough connections on firewall,,,
All dash gages read off of data link wiring,, or can wiring on the t 2000
I'm just following up to see if you need anymore assistance?
If you need a wiring diagram of ecm plugs from cab let me know
