You're back! Haven't seen you around in a while.

Iirc 70 bump stops were push in style, 71+ were bolt on style.

Grounds on shaker scoop all seem to be playing well with each other. The ground I have at the firewall is working as intended.

I actually threw a batter charger on the car while diagnosing the shaker, and now when I engage the switch, the flap barely tries to open. So I think everything is working, but possibly not enough voltage when the car isn't running?

With the vehicle off and battery charged, I get 12.4 volts at the battery, but only about 11.2 at the shaker wiring.
