I'm looking at upgrading to a green/blue PCM from my current red/blue 2000 P01 type. Looking at the pinouts, I ran into this: RED pin 13, Cruise Control Engage Signal, does not exist on either connector on the green/blue version, there is only a Cruise Control Release Signal (BLUE pin 33). Anyone do this conversion, or know how the cruise control works with a green/blue PCM?

Green/Blue are Drive by wire, and the TAC module receives the cruise on signal, not the PCM.

OK that makes sense. I've seen some info about 2004+ DBC PCMs, maybe those include cruise control.

Express vans used cable throttle up to 2007. I'm not sure if they used blue/green or blue/red.
Honestly it wouldn't matter, you would likely use the blue/red pinout for those regardless of color connector.

Well looking at the schematic for a 2005 Express van, on lt1swap.com (mega info), it shows the same pin 13 for CC enable. That is supposed to be a blue/green PCM. So I just had the DBW blue/green pinout, although can't find an actual DBC blue/green pinout showing that connection. but I guess it must be there and CC should work.

Hope so. I will be doing this swap in the next few weeks myself, and want my cc to continue to work. I know there are a few grounds that are different, and I heard I may need a pull up resistor to make the tach work.

yeah its pin 13 on the green connector. make sure it's a p59 with the IAC driver chip to be able to run DBC....and in the platform system options put a zero under ETC and do a complete write. read it back out and double check that ETC is off. 1=on 0=off
