Hello I have a GEN 1 leaf EM61 transaxle, the parking lock is still engaged on the transmission. Does anyone know the actuator pinout to control and release the parking paw/LOCK ?

Don't know about gen1 but on gen2 one usually uses the good old vice-grips.

The motor is some form of stepper motor and needs certain phase shifted signal to move. I have the actual motor and control unit if you want to play with it. I decided it was just too much trouble to use shaft locking. Imagine if my DIY unit would fail in locked position on the road!!! Like Isaac said i used pliers and rotated until i heared a click and i could turn the driveshaft by hand.
EM61 is really good motor, sturdy and compact. Built with no savings in mind
. Later models were all optimised built, cost vs performancewise...

Thanks for the response guys I think I will also use the pliers method. Once manually unlocked is there any chance if self reengagement with vibration?

No, it has a knee inside that motor has to overcome to engage the lock. I have used Leaf motor in my car as is for halfh a year now and i think i am good.
