Here is something i came up with, removing esc battery wires, as mine has still plugs.
Havent tried it in truck yet, to see if it will work.
Now i just wonder, should i still use CCBEC to power my steering servo, or should i leave it for MMM to handle.

I could have made it to have one pair of plugs less, but ill need that Y-harness to charge my batterys and those CC 6,5mm plugs are tight, so it would be pita to tear them off each time.
