Dakota Digital was a little out of my price range, but when I saw their RTX series (Retro-tech), I had to have one:
I also had to spring an X-link throttle adapter, which was another unanticipated cost. See, the truck harness has an 8-pin throttle body connector and the LS3 throttle body is 6-pin. Seems there's a little more to it than that though, probably something to do with the throttle signal coming from the PCM instead of the gas pedal/TAC module?
