[hypoxia]

Coach 1482 does have trailer/truck lighting with the trailer valve removed.  While being motivated to figure all of this out I finally ran a 1/4" air brake line to the toad coupling.  I just unplugged and capped the original 1/2" line & adapted the coupler to 1/4".  I have the M&G 2.0 which I haven't used since acquiring the Newell; it'll get used now.
