Agleader auto steer install

Im installing an agleader integra and steercommand in a 2011 760 and having trouble finding the can bus plugs from the lex. Also wondering where most installers find a good 12v power source in the cab as well as good ground. The combine has agleader moisture sensor but uses quaintimeter electric eye for grain mass. Not sure this is optimal. Any help will be appreciated..

TIA

BTW, it will use factory Auto pilot steering valve.
