Vts weird symptoms

94 XP: I bought the ski without VTS motor but VTS works flawlessly manually. I bought a motor and I get voltage where I am supposed to get it on the ski/ module side of the connector. I can actuate the motor flawlessly both directions with my power probe while hooked up....

Buuuut while the connector is connected together it only twitches both directions and when the engine runs it allows the vts to trim down only while stuttering with the engine rpms's.

Im pretty good with this stuff usually but I don't have a diagram to the module to see what components it uses. I assume some limit switch of sorts that im guessing is bricked and folds under super low resistance (usual motor operation), compared to when it hits the stops. TIA!
 
I could be wrong, but if I remember correctly, a bad VTS Control module has the possibility to mess up your mpem.
Unplug everything. Google, trim fix.
