The brake lights will either be the brake light switch... or the turn signal switch. 99% likely to be one of the two.
The tail lights... pull a bulb and see if you are getting power.... heck, just replace a bulb with a new one to rule out the dummy mistake. (yes... I've spent hrs troubleshooting only to discover the bulbs were bad)
If the bulbs are good, I say look under the bumer first, the harness was probably hacked up for a trailer plug. Look at the brown wire for bad connections or breaks in the wire.
Do your dash lights work?
how about the front parking lights? (which will only work in the parking light position, and turn off when the headlights come on)
