Cat 279c Electrical Schematic?

Hey I was wondering if anyone happens to have a wiring schematic for a cat 279C Skid Steer sn: MBT01024. I'm trying to figure out which button on the joysticks will run out to which pin on the deutsch's connector on the front of the machine where the aux hydraulics attatch. We have a snow blower attatchement that isn't cat branded and I'm trying to run the electronics through this connection point instead of running it off a clicker box and running the wiring harness over half the machine. I know bad set up, I can't even figure out how they were able to plow with it before but it couldn't have been fun. Any help would be greatly appreciated. my email is dsichewski@gmail.com.

Thanks!
David

My 257 owners manual has a diagram showing which wire number on the Deutsch plug corresponds to which control button, I don't have it handy today but can scan the page and PM you if that would help.
