How to turn off the DRL
 

Has anyone tried to turn off DRL on 2020 Mustang ??

i think if you go to a Ford dealer,
they will do it for you
they just use the computer
& reprogram the Smart Junction Box

(that's what they did with old models,
but phone & ask,
or phone a different repair place & ask)

but in some places, they are legally required
(like here in Canada)
