Headlight Low beam wire question?

I just purchased a V led DRL V3 triton kit and I'm looking to tap the dimmer wire into the headlight low beam wire, but I'm not quite sure which wire is the low beam.
From the top of the connecter you have the white common and 2 red wires. Is the low beam the middle or the bottom wire on the connecter? Both red wires have stripes on them. Your help will be appreciated.

 

Anyone have an answer ?

 

Get out a DMM and test both the leads. Best way to find out which is high and which is low.

 

Thanks!

 

I got out my volt meter after no responses the other day and the low beam is the middle wire on the driver side. I had 12 volts there with my lows on and nothing on the other 2 wires. I haven't checked the passenger side, but I will check before I tap into the wire to confirm.
