The 56 control switch and limit switches are under the car but fuses and solenoids that control the motor are in the space between the drivers side cowl and inner fender. There are some good photos of the mounted 56 components along with a very good treatise by John Lauter (Mr. Pushbutton) on how the system operates
starting here at post 235 and continuing on the next few pages of the blog.
It is somewhat risky to move anything without the limit switches being in the circuit but to manually move the car with the limit switch in the circuit involves going under the car and grounding terminals inside the weathertight enclosure of the control box. In an emergency you can move the car at the solenoids but that bypasses the limit switches so be very careful and just barely connect a jumper long enough to verify direction.
Assuming everything is wired and was working correctly use a jumper wire, one end connected to ground and touch the other end to the small terminal with blue wire on the top of the solenoid. That SHOULD cause the rear of the car to go down. It the rear wants to raise more or nothing seems to happen IMMEDIATELY break the connection and try the terminal with orange wire on the other solenoid. Only leave it connected long enough to level and then stop and start troubleshooting what has happened to prevent automatic operation.
