Activation Wire-ZEX
 

Got a question. A silly question.

Ive done the rewire for adding the 2k9 tb into the car. In doing so i had a sheet that detailed the tps wires. I know there are two, but without the sheet im kind of flapping because i dont have the listing of the colors. I can trace down further in the harness, and am curious WHICH WIRE DO I TAP MY ACTIVATION WIRE FOR THE ZEX BOX into?
I believe it is the white, but not 100%? i finished hooking up the dynotune control gauge, just need this one wire color. Thx.

White is activation.
