Installing new Autometer gauges

I am putting in a new Autometer speedo, fuel gauge and tach. I have put the gauges in cluster where the original gauges were. I am having difficulty u figuring out the wiring.
I have the instrument panel out and have plugged in the headlight switch and 4 way flasher switch. When I try the headlight switch, no lights. Does the switch have to be in the panel and the whole panel hooked up to work??

I want to hook up the gauge lights to the original panel light power so they operate with the headlight switch and panel dimmer.
Any help would be greatly appreciated.

Thanks,
