For others seeking this information:
In the auto wire loom that goes down to the trans, there is a brown/black wire (brown wire/black stripe). This wire has to be grounded. This wire grounds the starter relay (86pin) as if the car was in park or neutral. You can also do this right at the trans module plug, as it is the same colour and comes out of pin 26 on the trans module plug.
