hyster n35zr-16.5 hydraulics disabled/steer ok fault

i have a n35zr-16.5 that i removed the drive motor/drive unit to swap the drive unit with one from an identical parts truck we have. i also removed the steer motor when pulling the drive motor. everything went back together fine but now i have no hydraulics. unit says hydraulics disabled on dash. i went into the diagnostic system and performed the static diagnostic and under "steer ok" it says i have a fault. i tried replacing the motor and steer controller with the parts truck and found no change. also found a pinched wire going from the steer motor to the controller. repaired the wiring and still no change. any ideas on what next to do?

If it was easy, everybody would do it.
truck is fixed but just incase anyone else has this issue i called the local hyster dealer and they said hold down buttons 3 and 4 on dash to turn back on hydraulics. everything is working fine now.

Fact of the week
The use of "hello" as a telephone greeting is attributed to Thomas Edison. He is said to have suggested it as a simpler alternative to other greetings, such as "Do I get you?" or "Are you there?".
