I recently purchased a 1979 airstream. I'm not sure the model because it's parked out of state. I need to move it soon.
I'm trying to identify the name of the round black hook-up that allows my vehicle to activate the brake lights and turn-signals of the airstream. I failed to take a photo. I believe the adapters called "seven blade". Am I correct that this is what it's called? Are there any variations that I need to be aware of?
My vehicle has a flat four pin.
I plan to buy the adapter at a local chain store like Pep Boys or AutoZone. Does anyone know if they carry the correct adapter?
You're some examples of what I'm asking about
