got a 89 crx, recently hooked a tachometer and sound system. all stereo main harness was cut so i rewired it straight from the unit. now i put the system and tach in my gsr, somehow the tail lights doesn't come on when you brake and fuse no. 12 blows everytime you put in a new one. i recheck all wires and they are not touching and bulb it dark but not blown, replaced. need help how to get tail light to work again and stop fuse from blowing. (Same thing happened to my 95 ex coupe)
