1970 Cuda fog light and marker lights

Its it true that when the Road/Fog lights on a 70 Cuda come on the side marker lights should come on?

or the opposite - you shouldn't be able to turn on the fog lamps unless at least the parking lamps are on.

Activating the roadlamps will indeed turn on the marker lights as well as the dash illumination circuit...

O.K. I have checked everything and it works as it should. I have seen pictures of the Road light wiring and set up, and I do now have another question. In the pictures I have seen, specifically on MOPARTS there is a relay. I have a place of such a relay, but I do not have the relay. If everything is working right what does the relay do?

The relay supplies power to the side marker and running lights when only the road lamp switch is turned on. It does not supply power to the road lamps, the switch does.

So if everything is working as it should you've got the relay in place already or someone has rewired the circuits....Relay is positioned behind the ash tray area...

O.K. Thanks for the last picture, I see the relay I am missing is the buzzer one. Where can I get it and does any body have the part number?

Thanks for the help.
