Wires into late sunroof motor

[tony_ack 0]

I have a spare sunroof mech and panel that I've been trying to refurb, to replace the broken one in the car. The mech is all aligned and built up, cranks okay, and I have managed somehow to acquire 3 spare motors.

 

Ideally I want to test the motors on the mech, before I install the mech in the car, just in case I need more/better grease or in case the alignment is out (I don't want to install the roof, and have to remove it again to re-clean...)

 

I have a homemade electrical tester made from a car battery, switch and fuse, so I can hook it up to test it, however I don't know which wire does what!

 

Any ideas?

 

I've look in the Bently manual, and worked out some of them:

 

1

2

3

4 Total closure signal wire

5 Switch illumination (not sure why this goes to the motor - maybe the light is a diagnostic for the motor?)

6 Earth

 

Any idea what 1, 2 and 3 do? I guess they're all live, and as the relay is in the motor housing, I guess the feeds to these may form some sort of Reverse-Stop-Forward switch?
