Anyone link a discussion regarding the proper AlphaOBD set up for the Alpharex G2 Pros. Can’t seem to get the DRL to come on in Auto Mode during the day.
They work fine at night, and if I select parking, just not during light conditions in Auto

Did you run the wire to the battery?

Are you using their drl module? I have the G2's and I have no problem with the drl's not working properly.

As stated. You'll need to use the supplied drl harness for the drl's to work.

On the harness each red wire goes to the headlight going to the red wire coming out of the housing.

On the other end of the harness red to positive, black to negative on battery and Grey to a keyed on fuse.

Instructions and installation video are on alpharex.com

@erikr what headlights did your truck come with from the factory? Quads or Projectors?
