electrical problem (brakes lights do not turn off)

[cardboardbox]

s13 coupe, sr20 swap.

I was working on my exhaust/turbo system unbolting pipes and touching this and that. When I was done I noticed that my brakes lights refuse to turn off (unless I unplug the battery). I took it for a spin and also noticed that when I apply the brakes the floor lights flicker on and off sometimes. I'm not sure where to start when it comes to electrical systems other than the fuse box and battery. Any techincal support is appreciated.

you more than likly have a misaligned or damaged pinswitch

get under your dash there is a switch on the upper area of your brake pedal when the pedal is not depressed it shoud be pressing in on the button of the pinswitch if it is and the lights are still on replace it you can get them from an auto parts store it is called a brakelight switch
