Dimmer switch for 70 imperial with automatic light system

[fury1]

Hello guys it’s been a little while since I’ve posted on here. It’s just gotten nice enough out here in MN that I’m back working on things. The first on my list is fixing the headlights on my 70 imperial. They’ve never worked with the switch. Only ever used them with the automatic headlights. I tracked it down to the dimmer switch. I go to look and this is what I find. I’m assuming the automatic headlight cars got a special dimmer switch? Can anyone confirm? Thanks! I also seem to have no power to any of the wires that go to the dimmer switch itself

Very hard part to find.
Contact Mobileparts here, he may be able to help.
Or can your old switch be restored.

I agree it's a very hard switch to find. You might contact devilizm here on FCBO and see he has one.

I found one at Brads NOS - expensive but what could I do - it's that darn fourth connection.

Interesting...

I found these and not surprised they use the same switch. Note Mopar part number on first switch.
