I have a 1998 GMC Sierra pickup 4x4 350 Vortec, and I keep blowing a
fuse when I tow my boat, it's the number 15 that controls the das and it
also runs the trailer lights. Anyone ever had this problem before? if so
how can I troubleshoot it.


I had similiar problems with my 2000 Chevy 2500. I rewired teh entire
trailer and plugs and still had issues. I had a inline box under the bed
that the wireing harness plugged into. I replaced this box and solved my
issues.
