broken car starter

I have a 94 Cavalier, it has a remote starter that was professionally put in before I bought the car.  Well the other day i was on a drive on a very bumpy road and I  did something to my car, I have no dash lights, none,  any where.  And the remoter starter and keyless entry thing, (all aftermarket), don't work, when u press the start button the heater fan turns on, and some relay clicks, there is also a buzzing noise that doesn’t stop until u press the brake to shut it off.  If u press the un-lock button the main remote box clicks and then buzzes some more. But the power lock solenoid doesn’t click nor make any attempt to unlock.  I have no idea where to start, im hoping its not fried.

Any help would be great

well i put my old pro-start control box in and changed the fuses and it works again, im not shure my old box was even broken.  Everyithing works fine exept the dash lights. if u press the start button the car starts fine and the running lights come on along with the dash lights.  But the headlights or parking lights do'nt do a thing, the dash remains dark.  Not good for driving at night

Thaks for the fuse tip,
