VFR 750 F Brake light question

Hi all -

I'm trying to install a ST2 Strober (pulser) to my Brake Lights. Can anyone tell me which wire is the Ground Wire and which is the Signal Wire?

I have 3 wires going int to the taillight - stoplight:

• Green
• Green w yellow stripe
• Brown

The people at ST2 didn't know and suggested: "You can test the wires with a multimeter.
On the multimeter, you’ll need to find:
Power wire = 12V with ignition switched on
Signal wire = 12V when brake lever is pressed"

Since I'm not experienced with a Multimeter, I thought I would ask here.

Cheers – Jeff

• Green = Ground
  
• Green w yellow stripe = Brake Power
  
• Brown = Running Light Power

 

Awesome, many thanks for the help and the super quick response!!
