What’s this?
What has started as a Brake booster replacement has turned into a dash wiring clean up/repair. On the back of the Tach is this. What is it? I’ve poured over the AIM and cannot figure it out.
the item in question is on the Tach above my hand.

Capacitor Filter for the radio usually
The put a handful of them on the cars to stop radio popping, brake light switched, heater motors, etc. Usually spliced into the harness using scotchlocks (spl)
I've never seen one screwed to the gages, normally just taped up to the harness

The item in your first photo is the windshield wiper door vacuum solenoid switch. That is the gizmo switched on when you turn on the wipers, and it sends vacuum to actuate the wiper door vacuum actuator. It is a simple device: send 12vdc to it and it opens a valve allowing vacuum signal to head toward the actuator.

If you look again you'll see that he is asking about the other thing

rather than the tach solenoid
(And yeah that's one of the more confusing names, way back I thought it must raise the headlights at a certain speed or something...)

From the picture it looks like a radio noise suppressor capacitor. On the side that the nut is for the wire harness, there should be a little hole. The hole used to have a wire that came off of it and is now broken off. My capacitor is on the steering column but not sure where the real location should be. It should just connect to the brown wire for voltage.
