Ranger Mods

My brake lights on my 2016 PX2 XLT currently do not work. The position/park lights work fine, as do the indicators and the reversing light. No blown fuses, no error codes popping up. I have installed new bulbs but still not operating. The high stop light does operate.

I did do the parking light DRL enablement recently. Here is the setting I have in the BdyCM module for enabling the DRLs. Not sure if related or not.

Any advice appreciated as do not like driving without a full complement of working lights.

Edit: just hooked up the trailer, and the brake lights on the trailer work, leading me to think a wiring issue at the rear of the vehicle. have tried disconnecting the harness at the rear and reconnecting but no change.
Second edit: checked voltage at globe plug with multimeter and no power for brake circuit. Now to trace back through the harness, oh what joy.

Uninstalled the DRLs and brake lights started working. Not sure which entry caused the issue, as nothing seems to indicate brake lights as part of DRL activiation (eg not listed anywhere light fog lights, low beam, etc). Anyhow, was able to get DRLs working with brake lights also working.
