I am re-posting here since nobody replied under the general forum.

Did South Park come with a Shaker Motor option?
I have several open terminals in my cabinet and can't figure out what these connections are for.
If it did not come with a shaker, has anyone successfully added one?
I'm thinking about triggering with any of the 3 solenoids that move Kenny.
Thanks!

Well I will be adding one to trigger whenever I hit Kenny.
Wish me luck and I'll let you know how it goes.
Thanks

I have been meaning to share this for a while now but been too lazy. I added a shaker motor to my South Park and it works pretty well. I’m using a Stern shaker motor, (2) 5V relays, (2) Flash to Solid Boards from Tim’s Pinball Mods and a 5V transformer. Total spent is around $150. In hindsight, I would only need (1) relay and (1) Flash to solid board so this would have saved some money (more on that later).
The shaker is activated when the pop bumpers are hit or more specifically, when the Yellow Flasher near the pop bumpers goes on.
Sorry I am not providing a wiring diagram for what I did but I’ll explain these photos the best I can. I am not going to explain how to wire a relay or what they do but the Flash to Solid board will take an input from a flashing lamp and convert it to a solid signal. This way you can tap into a flashing lamp (in this case the yellow flasher near the pop bumpers) and the board will send out a solid “trigger” to the 5V relay. The 5V relay is wired to the Shaker Motor. The 5V transformer provides power to all these components including the shaker motor. The cabinet’s 115V source for the transformer is the black & white molex connector located right in front of the big transformer. Not sure what this is meant for but it was very convenient. I placed the motor in the middle of the cabinet and not in it’s typical space because it was a tight fit. This is probably not a good idea because the bottom of the cabinet shakes too much now. I’ll have to re-do this. Also, I used two flash to solid boards and two relays to tap into both the Yellow and Red flashers but this proved to be too much. The shaker was going off all the time and I didn’t like it so I disconnected the connection to the Red flasher and like the effect now.
If I did this again I would obviously only need 1 relay and 1 flash to solid and I would move the shaker to it’s typical location.
I hope this helps anyone who may want to try this.
