Hi. Got a HS2 this past weekend and a previous owner at some point had installed a shaker motor in it. I am having trouble finding any information on how to wire it up since the only wire of the 4 coming out of the motor board that is still wired up is the black to a ground harness....the other wires are purple blue and red and not attached to anything. Hoping someone can point me in the right direction! Looks like a pinbits shaker motor.

I found the instructional on the pinbits website. Looks like whoever installed it followed them correctly for a williams machine (clipping 4th pin since only 3 are used on WPC)
The instructional says to wire to the 20v flasher on backglass panel. Here's the link:

I am hoping to find someone who has done this since I tried several times and still can't get it to work.
