Well..... I've been looking at the C2 connector and the instructions written up and I believe it's more than I want to bite off. It seems easy enough but the way my luck runs I know I'd screw something up and bee into it for a lot of money to fix my errors. Would I also need any kind of tune with it after it was wired up correctly? I wonder if there is an EFI tune or something similar that would do this without having to do the wiring to the C2 connector? I'm just not sure of my abilities on this one.
It isn't really that difficult. You are not doing anything to any other pin in the connector. The fool proof method of insuring you don't mess something up is to disconnect Both Neg battery cables before touching the connector. Then leave them off til you have everything else back together
The diagrams in the threads I have linked show you precisely where the #53 pin is located.
But if you study it and are not comfortable you can always get some mechanic who is comfortable with that to do it for you.
If all you want though is a stock tune with the Turbo Brake activated Rob at ATP Trucks can probably write a Stock Tune (No Deletes) for you.
He cannot "tune" trucks any longer but they told me they could help me with a stock tune if I wanted one. No EPA problems with a stock tune and a TB that I can envision.
