What is it best to wire up a boost gauge as i have done the following:-
orange to lights
red to 12 volt
black to earth

i have fitted it to the fog lights but it doesnt work right
when i turn the lights to dip beam the boost gauge comes on but if you turn the lights on full then it switches off
also there is no change in the light from ignition to when you put the dip beam on.

 

Just use the light feed wire for the cigarete lighter mate.

 

Mine goes to the ignition live on the stereo

 

just put into the lights mate you only need power and earth that way if the lights get power so does the boost gauge mate
or alternatively try wiring it via a cool looking switch board mate like a toggle
hope this helps

 

sorry its a smoke one so i need to wire the red to a live black to earth and orange to the lights what i mean is i want to use the wires on the fog light switch but which wires to put the ones on the boost gauge

 

Mines the same, i spliced both red and orange together, then wired them up to the stereo ignition switched live, easy job!

 

does any body know which wire is the live and neutral on the fog light switch

 

Yeah mine are smoked too and like Mit they are wired to the stereo

I would suggest you get your self a multi-meter or circit tester before you blow some thing fella, it really is a piece of pi$$

 

Think I tied mine into the top outer 2 on the switch.
Use a multi meter to test it takes 30seconds to do, mine come on with the side lights ie fed from the lamp inside the fog light switch.
Fixed live your best usign the stereo, red lead I think.
