Perfectpass wakeboard cruise
 

I have a perfectpass wakeboard cruise module (older paddlewheel only model no rpm mode). The servo motor is new and the two button (non-led) gauge is also new. The module is used. I do not have a paddlewheel but am using a nauticlaugic nl4-pp gps unit instead. I am pulling power from the ignition (putple wire) and grounding to the grounding block. For some reason the perfectpass will not engage. The perfectpass seems to mess with my tach as well (rpms climb and climb regardless of engine speed). I can't tell if i have a bad module or a bad install. If anyone has an old wakeboard cruuse module i would like to purchase it. If you have any ideas what i could have done to mess up the install i am all ears as well. Forgot to mention the boat is a 2000 Malibu 23 LSV. Thanks!
