Thread: What are these please?

The two under the wipers I think are for a heated windscreen altho I could be wrong the other is a fuel cut off switch from what I can recall it resets the fuel system after a accident I wouldn't push it.

Don't know about the plug but the button is associated with resetting electrical isolation which automatically occurs in the event of an accident or sever jolt to the vehicle.

Pushing the button will enable the car to be started again if it has been electrically shut down following an accident.

Ok I won't go pushing the button just to be safe.
I am pretty sure the plugs are not aftermarket because the lead back in to the main loom

As correctly noted above,

The 2 plugs below are for a heated windscreen, not optioned in Australia,


The switch on the firewall is called an inertia switch, which trips on impact and shuts down the fuel to the engine. This can also trip on the rare occasion when hitting a sharp cattle grid or dip. The symptoms are, the vehicle will stop and the hazard lights flash. All is OK once you push down on the top of the switch which resets it.

Funny this question about those two plugs is asked..

I was working on my bus last weekend and my Father In Law asked the same question..

We decided that they must be for a large current as the diameter of the wire is much bigger than any other wiring under the bonnet.

So heated windscreen makes sense.

But maybe a more experienced person here can confirm or deny this rumor.

That's not such a bad idea. I wodny mid fitting one to my race car for safety.
