I bought a teryx that the dealer installed some engine upgrades on, and when they put it back together they got the 4wd actuator hooked up wrong. they said they will fix it, but I dont want to haul it back over there. Can anyone tell me where the vuccume lines hook up properly? I hooked the line from the motor to the bottom of the solenoid, then the middle line on the solenoid is going to the actuator, The line out of the very top of the solenoid is going to a vent with a plastic cap on it, and the bottom of the actuator has a line going up to another barb on the shifter bracket that does not go anywhere. The 4wd engages now, but it seems really slow to engage. any help is appreciated.
