Hey guys, Changed the demister switch over from the one that wasnt working.
Found out it was because it was coverd in gunk from the gas switch. But after changing it the gas system lights are on but it doesnt switch to gas. Must have done something to it, not sure what though......

Here are some photos, HELP!! Please of course.

Does anyone know if most of these switches are generic or what the go with them is?

there should be another wire or two going to that switch....

Ahhh you tell me that now! haha...
I called up the supplier (once i found who made the bloody thing) and they told me the exact same thing. It had fallen behind since the wire was probably about 20mm shorter than it should have been.

Thanks for your reply mate, its all good now. sorta

The supplier gave me these for future refrence if anyone is interested.

From left to right (left being the red l.e.d. side and right being the green) each wire should be

Signal 0-90ohms, Gas Terminal, 12V Ignition wire, Petrol Terminal, Negative.

My system must have a relay that breaks contact for the fuel when the gas terminal gets voltage thus the ommission of a wire to the petrol terminal.
