Fuse #13 keeps blowing
Every time I step on the brakes, there is a bright spark in fuse #13. My brake lights, turn signals and hazards don't work. At this point my truck isn't drivable.
According to the owner's manual in my truck, says circuit #13 is for "stop lamps, CHMSL/hazard, trailer tow stop lamp, and speed control."
I'm assuming that the hazard part covers the turn signals as well, but I know the cruise control works even when the fuse is blown. I used it last night on the way home (this was before I realized I didn't have brake lights).
So I know I have a short somewhere. The only mods I've done to the lights are the aftermarket headlights, but if the fuse only gets blown when I step on the brakes, I don't see what that would have to do with it. Also, these lights have been installed and working for about a month before this started. The only thing that I did around the same time was install the gauges. I ran the power to them from #5, the customer access circuit.
Are there any other "common" areas for this to happen? I already removed the rear brake lights and it didn't help. I am quickly running out of 20A mini fuses.

Sorry to hear about your problem, I'm sure someone here will chime in with ideas for you. In the meantime the good news is you can drive it that way in Miami, that's the norm down there.

On the trucks the chmsl wire is usually light green and is at the rear my the tow package wiring I assume the EX has that same harness. Maybe that wire has been pinched somewhere along the lines.
Also, possibly one of your bulbs is blown and the power side of the filament is laying down and touching ground in the bulb.

That was the first thing I thought of. I already removed the rear lights. I'll take a look for that wire though.
I am going to check under the dash for a loose wire. This started happening when I wired the power to the gauges so it really seems like it would be in that area.
