I bought a new pinbits MM shaker kit a few weeks ago and finally got around to install it this past Saturday. It is funny because the pinsider I bought this from didn't have the heart to install this on his HUO MM because it involved making permanent modification to it such as mounting the shaker and interface board.
I ran the first part of the harness down the left side of the cab and then up to the lower left playfield. There are basically 3 points that trigger the shaker to be interactive during game play. Pinbits has premade molex connectors to intercept signals to send to the shaker when triggered that don't require any permanent modification to your game.
The first one is the catapult coil
The second one is the castle destruction coil which I had connected to the coil which controlled the castle gate. The pin out didn't exactly match or make 100% sense so good thing Drano was still up at 11:30pm when I shot him a quick text to confirm on his MM.
The third one is the optos which get triggered when you hit the drawbridge or gate
The only part which was not plug an play was getting the +20V from flasher on right hand side of playfield. Not a big deal and just have to make sure you are soldering the red wire to the proper side of the socket and easily reversible in case you ever want to remove in the future.
The last step was routing and running this ground wire to the back of the cab and up into the head. There are a few things grounded right in front of the MPU.
I played a ball to test out to make sure everything worked and called it a night. I just have to make sure the shaker doesn't interfere and trigger the tilt bob and adjust accordingly if it does. Anyone on the fence about this for their MM, AFM or STTNG I would say go for it because it integrates nicely into the game play. It's a bit pricey but not that much more compared to a Stern shaker these days at $195usd+shipping. This pinbits shaker kit is very well put together much like all their other products. You can tell a lot of thought was put into it because it came with everything required for the install and length of each wire in the harness was perfect.
