no dash lights

pulled cluster today and cleaned all contact points. Amp wires are the ones with wire nut, plan to replace wire & heat shrink. Have power at fuse box & headlight switch but could not find power out from the barrel connector.
Cluster looked good, tightened all nuts, cleaned cluster and fuse box. Found the emergency flasher fuse was blown. I had replaced that last week after finding flasher was disconnected. Plan to replace the flasher switch also.
Now, to see what happenings with power to barrel .
