    So does the passenger side feed in somewhere? Is it this piece? Or is this something different?

    Maybe next is photos of the headlight with stalk on drl where we can see the mirror, then switch to park, another shot, then to low beam, another shot. preferably in low ambient light?

    This is the drivers side v5 wire.

    The passenger side feeds through the passenger firewall, which I realized I should have went inside and meet up with the drivers side and then go through driver side firewall. I did check each position in my garage at night without the garage lights on and the DRL brightness does not change.

    So a photo of where passenger and driver are embracing perhaps? Still likely a non-issue. I think next step is to observe headlight with mirror light in the frame across the stalk settings, I see no problems so far so I want to understand the behavior you are seeing light-wise.

    I was able to test the v5’s DRL dim and brightness modes by connecting the red wire first then white wire to the positive post of the battery using a 5a. Fuse in between and they work. I’ve now seen the difference in dim and bright settings. So it seems the v5’s are in dim mode no matter what the position is at the stalk except for off position. This also means that the white wire is getting the +12 volts and the red wire isn’t. I was able to confirm this using a meter.

    How is it then possible for +12 volts (white wire) to be present at all stalk positions except off?

    OFF - No current
    AUTO - +12 volts white wire, 0 volts red wire
    DRL - +12 volts white wire, 0 volts red wire
    ON - +12 volts white wire, 0 volts red wire

    The 2020 LED headlight DRL does not change in brightness in any of the stalk positions. They are just on, not sure if it’s bright or dim.

    Did you confirm that the vehicle was ON, and the parking brake released when you cycled the stalk switch?

    I have a 2020 and Dave’s T harness. I struggled with figuring this all out. I found that parking brake off isn’t enough, you need to take it out of park and put it in drive/reverse, and then a few seconds later the mirrors signals change brightness.

    I also noticed the behavior changes when I was testing at night, vs daytime. I believe the ECU takes into account whether there is “daylight”, so stalk position in DRL position isn’t the only thing to account for when testing.

    Correct me if I’m wrong on any of that, but those are my observations so far.

    I was driving home thinking about that as well, I’m glad you brought it up.

    Last night I drove forward and reversed, put it in park with no hand brake but nothing changed unfortunately

    Since you tested one lamp, I'd say the issue is somewhere in the connection to the headlights.

    @caribe makaira the stalk in @mokeiko looks different from the one in my truck. Mine has Off, DRL, park, low and his says “DRL off” then auto then park then low. Is that maybe Canadian style? Or just auto headlights introduced in 2017?

    Hello,

    my 2022 SR5 has turn signal mirrors. I don’t need to do the whole DRL install route. Just want to wire them through window switches.

    I looked at the install write up on meso customs website, but can’t figure out which wire to tap into for the window switches. The colors are different and sadly, I don’t have a voltage tester at the moment. Also, My window switch doesn’t have the Auto function, so I have less wires on the connector.

    any help would be appreciated!

    Anyone in the same boat have experience?

    much appreciated! I will return my double t connector and get t taps.

    Had some time to properly read the thread. Am I right to assume that:

    Passenger side is the p14 connector and i should wire to pin 2 (bright function-white wire) & what about pin 6 for dim?

    Driver side is the O1 connector and should wire to 7 & 8?
