[T3] a wiring question

[David Sanderson]

Hi Bob
Thank you for this - you're correct on the wiring. In fact, the 911  
also has this capacity to keep a side-marker light on when the car is  
parked and the turn signal is still in position. On the notch I'll  
wire these lights to the parking light circuit I think. They look cool.
Cheers.
Dave
