Dodge Cummins ECM plugs wiring diagram

OK, I think I have asked about this before, but surely someone has to have this by now. I need a diagram or schematic or at least pin description for all of the pins on the ECM plugs on an 05 Dodge with the Cummins engine. I have access to Cummins schematics and pin diagrams for every other engine, but they don't release the info for the engines they sell to Dodge AND they make them different so that the pins don't refer to the same controls. I want to add a few things like a switch to manually turn on the cooling fan and I want to have a few other things eventually that are available on the Cummins ISB engine, but have to be accessed or controlled directly at the ECM plug. Also I want to run a switch separately to a common control panel for these items in the dash and integrate my ground signal for the high idle enable switch (ground that bypasses the $300 clutch switch Dodge wants to sell those of us with the manual trans).

SO, does ANYONE have a link to a Dodge Cummins ECM wiring diagram? OR if you have one on your computer or on disk, please email it to me- PM for my email address if you have this. Thank you.

Go to this web site http://www.hemitruckclub.com/ and scroll down the left side of the page. You will see links to download the manual of your year truck. Be ware this is a full shop manual it will take a long time to download. It has gas and diesel combined in one manual. There is a block diagram with pin outs on it. It doesn't show someof them like the one for the fast idle. If you glean any info from it please share the love.

I have read and read that manual. I just can't find an actual diagram or pin description for the ECM. I have even tried looking for testing or actuation functions for special functions like fan engagement, but to no avail. I hope someone just has a pin out description for the Dodge version Cummins in 05 so that I can just use that. I really wish that they would not have messed with them and just let us have the same ECM pin pattern as the other Cummins engines.

That is absolutely the best thing that ever happened to me- today at least. THANKS!!!!!!

OK, a little more technical..... Plug C2- Pin 43 K160 is an 18 gauge wire, color is Brown and Orange- it is the Fan Clutch Control. The question is- is this a 12V output to the fan clutch? I figure it is variable to control the fan clutch at different speeds, BUT maybe it is just a 12V output to turn it on full speed when needed if the Viscous control does not engage it enough???? Can I just splice in and apply 12V to this circuit to make the fan engage at full speed? Would I need to put a diode in it to keep the 12V signal from feeding back into the ECM plug when I provide that 12V from an outside (battery/ switch) source?

me1mango,
Did you figure anything out on the fan clutch? I think I am having trouble with mine, and I would like to check it. I know you wrote this a year ago, but I figured you had it worked out by now.
Thanks,
