I would not recommend using a connector such as that on both the input and output side of a Jaguar, or any speed controller. You add resistance and another point of failure. Run all wiring directly from the PD board to the Jaguar, then from the Jaguar directly to the motor. If the motor has built in leads, crimp on a quick connect there and only there. The only exception is if a large portion of your robot must be removable, then having mass quick-connects or a terminal block there would help. It isn't that hard to screw in a fork terminal, so having those connectors provides no advantage. If you plan on re-using the Jaguars from year to year, you can always unscrew the fork terminals and pull it out, it's not that hard.

It isn't clear to me if the Black jaguars are actually a better product, but after the problems last year my team is only buying Victors. We will use the Jaguars that come in the kit, but no more. All Jaguars can handle CAN, so having more than 1 Serial-CAN Black Jaguar isn't helpful. The do look nicer, but when they're buried in the chassis, do looks really count?
