How do I use mech. brake w/ tekno conversion?

[raptor50]

I have futaba 3pk and the conversion.. Using Mamba max esc and I also have the CC bec and i want to use the mech. brake that was designed for. channel 1 is for steering, 2 is for esc and 3 is for the bec. then where do I put the plug for the mech brake? do I have to use a y connector or something? also, does any one know how to progrm the radio to use in conjunction to use brake servo and the motor at the same time?


one more thing.. how do I get rid of the brake in my ESC?

thanks..
