for the interior lights it sounds like either something in the wiring harness, headlight plug, or headlight switch. Also check the fuses. The gauges could be a number of things but it sounds like you are not getting power out to all these items. I would also make sure you have all the harness grounds properly grounded.

Light Switch Wire Colors

Here's a pin-out image I made of the light switch for my '67. Knowing Ford, the wire colors on yours should be the same.

Does the cargo light switch **** light up red when you pull it out this is on the dash, Dark Red **** switch for it?

Dash Cluster lights are controlled by turning headlight switch **** right to lite up & left for off.

Dash Gauges not working or showing much movement mostly little small voltage regulator backside of dash..

Ok you may need to remove cargo light cover and remove light bulb from the socket, clean socket replace bulb as needed as they hold moisture inside and don't make a good ground contact..

Also check for 12 volt at the cargo socket..
