No dash lights

Trying to get the dash buttoned up...installed all new bulbs

Pull the switch and no dash lights. Checked the Tan wire at
the light switch and my test light comes on. I have an orange
wire with a clip on the end going nowhere. It is wrapped with
the wires going to the flasher. If I pull the light switch this
wire becomes energized. Is there a feed wire that needs to plug
into the back of the cluster somewhere.

Thanks for any info you can give me.
