So, you'll want to tap the output that will be powering the vehicle contactor and run that to another small relay. Then use that relay to switch your additional contactors with a new fused 12V circuit.
Chances are good that the relay will not handle driving 2x the normal load, but a small relay should be a marginal increase over the stock contactor load.
Let me know if you need/want a diagram
