I might suggest a hybrid connection where all the high current connections are made through PowerPoles which can be keyed for foolproof mating and a smaller connector for controls. Check Digikey and you will find that manufacturers like Molex make mounting hardware for their connectors as does PowerPole. I have seen (and inspected) teams using this configuration that were legal under FIRST rules. One caveat is that the assembly is now part of the electrical connection. If you do not have some way of holding the electrical connectors together they will become intermittent during competition.
