Zig Wiring questions

1- The fridge (for 12v)shows + to #12 and - to chassis. My fridge has a + & - & earth. What do I do?

2- I have no need for a TV or an electric pump, can I easily wire in a car stereo in place of one of these?

 

What fridge have you got? On 12v I'd only expect + and - connections.

 

Forget the model number.

Looking at it earlier it had a flex with a plug attached to it (240 v) and the other flex was smaller and had three wires in a connector block which I presumed would be 12 v. I will check again tommorow though.

 

Could be something to do with the igniter if it has one.

I would assume it can be wired either way, wire it up for negative earth .
