I,m not sure about your wires color.

3 wires:
Black: ground
Orange/White: to fuse box and module
White/Red: Shorting bar

I'm not sure about this one, but if a was in your situation, i will try (there is still a fuse protecting the system) grounding the black wire and connect the other two together. What i think will happen is that you will ground the dimmer and bypass it which will result by having your instrument panel lights at the highest, which is not bad at all.
