New Gauges?

[benton101]

i have bought some new gauges from R-spec
the gauge seems okay to hook up but on the power cable there are 4 wires
1xred
1xbalck
1xamber orangy colour
1xwhite.

i got told i need to hook the red up to my ignition cable so the gauge lights come on with it. the black is earth obv but what do i do with the other two?
cheers

Do you not have a wiring diagram?

[benton101]

it tells you wher to put the plugs into the back of the gauge but not where to wire it into

[AlexW]

Does it not tell you what the wires do?

[benton101]

No!
or i wouldnt be asking mate

[AlexW]

I guessed but its worth asking. Cant do much but guess, im presuming one of them is a headlight on one (May dim when you turn lights on, or turn on a extra light), and the other may be perm live (have seen it with a aftermarket gauge.

Hope somone can help you.
