Ok my tail lights just stopped working.
7.5a fuse is good
and headlights, brake lights, turn signals work.
just the tail lights don't work.

I spliced into the tail light wiring a power wire from my 500w AMP for a temp fix.

What else could be wrong??

 

You have an open on your power side of the brake circuit after your fuse and before your splice into the amp. Thats if you know your getting power to the fuse.
