Slight deviation here: On my setup, the Roadmaster pins were of slightly different design, but same purpose.
But there were connections also between the bar and the MoHo, and between the brackets and the Toad. All with locking pins.
However, I secured the other pins with padlocks, not the wire jigglies. You just never know when some miscreant will mess with them, or loosen the wirelocks. Each setup is a bit different, but the plan remains.
On the other hand, you don't want to padlock those big main pins, in case you have to release the toad in a hurry.
