The hideaways relay are allways with points closed, maybe on open or closed position but always gets some points closed.

It also needs to be grounded to chassis. If it doesn't get a ground the relay won't work. It should be howerver allways with points to close position by default

On closed doors position, the blue wire will keep energized the wire that closes the doors and is the motor what cuts the power internally.

Once you turn in lights ( green wire is the trigger which comes from headlight switch ) the relay will change the points position and now blue wire will feeds the other wire running to motor. Once motor gets the new signal, will spin on opposite direction untill get cuts again, BUT wire keeps energized.

Now you know this, you can easily bench test the output to motor both in open or closed doors. Remember the relay needs to be chassis grounded

A 5 pins bosch relay can be used to replace the stock one being wired like this:

30- blue wire Run circuit ( using the breaker in line to terminal 30 )
85 and 86, ground and trigger ( green wire ). Can be used in either way but tipically 85 is used as ground.
87-wire to open position
87a-wire to closed position

I made this diagram long time ago
