The green/white wire worked like a champ! Used the torx for the ground - now my V1 is happy as can be!!
Thanks for those awesome instructions X5Mod!!!
Took me 5 minutes to pull back the overhead light module, used my fingers to pry it from the front (it hinges at the rear).
Just slipped a thin black rj11 wire through the front against the windshield to the v1.
Plenty of room up there for all of the components.
