Forum Discussion
From another board:
it is all in the owner's manual under roadside emergencies.
pg 333:
fuse 37 pass fuse box = trailer brake control
pg334:
relay 6 underhood = trailer park lamps
relay 9 underhood = TT battery charge relay
fuse 17 underhood - trailer brake control
fuse 37 underhood - trailer left stop turn relay
ect ect ect
check out fuse 67 under hood listed as TT park lame relay power.
and fuse 73 underhood listed as TT stop/turn lamp relay power
looks like they are using a couple fused circuts to power a couple relays for TT wires.
