Do you think you could elaborate on your situation? I recently did the swap and the overhead console is only reading ccd. I know it's because of the CTM but if I don't have to swap it out that'd be great.

Well there are two wires that come from the console that are for data for the ECU. Instead of trying to find the correct ones and cutting in to them I just shoved them in the front of the ODBII port, same thing. The other wires in the console are for temp, and a couple other things. If you use the ODBII like I did the compass, and fuel economy, miles to empty will all work as it pulls from the ECU. I have to find a wire diagram of the ODBII port to figure it out again. I think it is the two top right or bottom right or something like that. As I said I can't remember.
