housing for 10 gauge wire

hey, i am in FIRST robotics if you know what that is, my team is in the process of building our robot and im in charge of wirering the thing, when we go to compete we ussually have to pull out some of the electronics and mess with them so i figured to make things a little easier, make the entire robot controller and speed controllers, circuit breakers etc on the same board and all of the outputs to the motors go to a wire harness that we can easily unplugg when we need to...........buuuuuut the biggest problem is finding a wire harness that can have like 20 spots for 10 gauge wire..........does anyone know where i can get a wire harness this big if it even exists, and any number over like 5 per harness is usefull, as long as its for at least 10 gauge wire.....

 

THANKYOU!!!

hey, i see some connectors that might work for me from that place in the last post, but where can i actually buy them from???? it seems their website only gives descriptions of the products but doesn't sell them directly, can someone direct me to where i can actually buy them from????
