> did this do you any better than if you had searched a youtube video or some other source?

Yes, because when I searched youtube for "miata wink mod" almost all of the results were for kits for microcontrollers which I wanted to avoid because I just want to control the motors with switches. Now I know to include "SPDT" in my search and I can find more targeted videos that add an override using switches.

The video you linked is relevant but doesn't really match what I want to do. The NA Miata has a motor for each pop-up headlight. There's a dedicated button that controls the headlights popping up and down but the light switch on the turn signal overrides this if the lights are on i.e. the relay is DPDT that's an OR of the 2 signals.

I want to add rocker switch for each light where the signal from the rocker switch overrides the behavior from the existing relay. If a given DPDT rocker switch is in neutral then the signal from the relay is used but if the rocker switch is engaged in either direction then the motor moves in that direction. ChatGPT did explain a lot about the default behavior and included a lot of the terminology that helped me confirm that. Of course, if I already knew about relays then I wouldn't have needed any of this, but I didn't.
