so just wired in the zener diode to the G wire so my brake lights are not affected by the 10v being sent from the cruise unit.

just re-tested to confirm everything is in complete working order

key on, engine running, connector unplugged to test leads:

A- off position - 0v
A- on position - 12v
B- (with A still "on") 0v resting; 12v momentary toggle down pressed
C- (with A still "on") 0v resting; 12v momentary toggle up pressed
D- 12v resting; 0v brake pedal pressed
E- 0v (ground)
F- 12v regardless of toggle A position
G- 12v brake pedal pressed
H- n/a
J- n/a
K- 11.6v
