2001 Honda Odyssey brake lights and dash lights won't work

Just had the transmission rebuilt for the 2nd time.1st was at 108,000 and the 2nd time at 195,000. The EGR valve was just cleaned out and finally no lights showing "check engine." The problem. Was trying to get my cup holder drawer out and it was jammed. Found out that it was jammed on the new stereo wires that my boyfriend put in in December. The stereo went off and then I noticed that at night I did not have any lights on my mph display so I couldn't see how fast I was going. Then a car pulled up next to me to tell me that my back lights weren't on at night. My headlights work and when I hit the breaks those lights work. So my boyfriend pulled the dash out and fixed the stereo and wires and put in new break lights but they still
do not work. Ordered dash lights from honda because those were blown. The lights on the mirrors do not work but the inside van lights work? Checked the fuses and none were blown. My boyfriend thinks it may be a fuse with the running module? Where would this be located and have you ever heard of this?
