brake lights on all the time...

man I hate electrical gremlins!!

you have 1 of 2 problems somewhere. the hard part is always finding out WHAT, and WHERE!

either A--you are getting power from somewhere into the wires that feed the brake lights or turn signals. could be a short, or wires hooked up backwards/incorrectly. or B--you're getting backfeed, where positive electrical current seeks out the shortest ground, even if that means going "backwards" up the ground and into the lightbulbs.

I had a problem one time where a crusty light bulb socket created a bad ground, and my parking lights were actually grounding up through the turn signal switch in the dash, which also lit up my turn signal indicators. talk about weird...turn the headlights on and both turn signal indicators would light up solid.

you might have something like that going on as well, so also check for bad grounds all over.
