1979 VW Bus Teslafied
I'm using the T2C controller with a Tesla small rear drive in a VW bus. I want to use the regen function for brake assist and to extend my range. The manual describes connector Pin G2 as "Regen Enable Switch Input". What is the that pin connected to and what causes the regen function to operate? In a Tesla car, simply releasing pressure on the throttle initiates regen. Same here?
