Bonding grounds are meant to tie any and all exposed surfaces together with a guaranteed path to ground (screws and wires), that eventually connect to the main ground of the appliance. They insure that should any condition occur where a hot wire touches an exposed panel, a circuit is made directly to ground which will terminate incoming power immediately (trip breaker/blow fuse). There is really no "wrong" place to put them except with any wire that is part of the circuit (black,red, or white wires). The appliance will not operate any differently in their absence, but they are to be connected to reduce possibility of shock hazard. They are always identified by green jacketing, or bare wires.
