split relays help !!

i have wired my split charger which is working ok but need to know if i need another relay for the fridge 12v supply or is it ok to rely on the three way switch on the fridge ?

Mickey,
I piggy backed another relay on the split relay so that the cool box only gets 12v when the motor is running.

I have two separate relays off the same trigger wire as per Titus above. You can run them off the same relay but you'll need a beefy relay as the fridge draws about 9 amps and heaven only knows what your leisure battery will want if you run it down a lot. Other disadvantage is if it fails you lose both.....
