apexi pen style auto timer

so 3 wires cant figure out which one does gray got to, which one does white one go to, and which one is black probably ground

Black is ground, grey goes to your e-brake for that signal, and the white goes to an o2 sensor signal.

 

thanks for help will hook up tomorrow

 

Tyler is right, but forget about the ebrake one its just not worth it. and the O2 sen. is narrowband and is about as accurate as a shotgun, so dont rely on the numbers

 

yep just dong the plug n harness and ground

Ebrake wire isn't worth it? It saved my ass 6-7 years ago from stalling my Nissan without having the ebrake pulled since the car was parked in gear. Its easy to hook up so just do it right.
