I have an 03 Suburban 1500 which I recently purchased that has the
towing package. Today I connected a trailer brake controller to the
trailer 6-way slot on the instrument panel block and noticed I wasn't
getting any power to the brake controller (no light on controller when
brakes applied). I then plugged my trailer's 7-pin connector into the
Suburban and the trailer brakes were not being activated; however all
the trailer lights worked fine.

The owner's manual mentions a trailer battery feed fuse is needed. Is
this the fuse that goes in the underhood fuse block in Stud 1 or 2?
Stud 2 has a 30 amp fuse but there's nothing in Stud 1. Any other
thoughts?
Thanks.

sides. If you find one stick a fuse in it and then test the controller

Stud 1 is for the trailer power. Also be sure the controller harness is for
a 2003 + and not a 2002 and older, they changed the pinout of the plug in
2003.
