Headlights not coming on

[shutudown4]

1968 barracuda headlamps will not turn on
Could it be a ground issue? The dash frame is not installed and the all dashboard switches are lying of the floorboard
I’ve been going through the wiring to check that things are correct
Does the switch need to be grounded somewhere?
Is there a fusible link involved with that particular switch
Thank you

Do you have ANY power in the interior? Do you have the big red and the big black ammeter wires jumpered togehter? BE CAREFUL, neither is a ground
