70 cuda road lamp wiring diagram

Does anyone have the wiring diagram that shows how the rad lamp switch, relay and lights hook up.

the factory service manual maeks it look like there is only an accessory power feed going thru the switch out to the lights. But this picture

shows the relay like I see under my dash but its not shown in the service manual (unless I missed it)

There is no wiring diagram in the 70 FSM for the road lamps that shows the relay or the roadlamp wiring harness.

Updated harness picture.
