2007 dodge ram 2500 dimmer 4 boost gauge

I need to know what wire at the back of the headlight switch I can use for the + on my boost gauge so it will dim with all my other gauges. I have two white with green striped wires, two orange with tan striped wires, and one other one that I think is brown with an orange stripe. One post I found said orange with white stripe, but I have no such wire. The truck has factory fog lights. Any help would be appreciated.

I found the correct answer. There are actually 6 wires in the connector. Two orange with BROWN / tan stripes, two white with green stripes, one white with a yellow stripe, and one black with an orange stripe. The correct wire is orange with a BROWN / tan stripe. The stripe can actually look purple depending on the angle. Since there are two of these wires you must be careful and select the one beside the black wire with the orange stripe. I hope this helps someone in the future.
