How do I hookup two different crawler brushless motors to one receiver?

[Jakyat]

Hey guys,
Looking for help. I'm building a KW 8x8 oilfield bed truck. I'm running novak"timbuk2" 18.5 combo for the main power train, and I've got a novak goat 21.5 brushless combo for the main winch. I'm not sure how to hook up second motor to run on its own esc. Can I just plug and play into my choice of channel? Do I have to provide another power source to run thie aux esc? If so, will there be problems with these batteries working against each other?
