Witch wires should have power/ Map switch

The delay thing is solved with your diagram, as is the map light switch, as the 74 diagram shows the internal wireing

All of the Pink is power to the lamps and right side of the delay relay

Left side of the delay relay goes to the ignition lamp. When you open the door, this grounds the HEATER in the delay relay, and causes the bimetal strip in the relay to close the relay, holding the ignition switch lamp on

The map light switch is shown "OFF" and is brought on by the door switches with the rest of the dome/ courtesy lamps. When the switch is "on" the wiper rotates to the "ground" terminal and turns the map light on directly.

But the OP hasn't been back, so who knows??
