TRD Gauges Help needed

Hey all

Me and my boyfriend have bought 2 TRD gauges, and oil pressure gauge and a oil temerature gauge, and the control boks that comes with the set. But we can't seem to get the light to work.

Here is a link to the gauges that we've bought.
TRD SPORTS METER LINK SYSTEM

There are 4 wires.
Black - witch we have connected to a constant ground connection
Orange - is connected to igniction
Red - is connected to constant plus
White - is not connected, but he thinks that it's for the light dimmer.

Our problem is, that when the power hits the gauges, the light goes on, and the needle goes straight to max and then down againg and the light goes off, we have pressure ind the gauges so it is just the light that we can't get to work.

So now we're wondering why we can't get a constant light in the gauges.

Anyone how have those gauges, and have installed them that can help? :)
