where, oh where?

i have a 93 eighty-eight and i need to know where the com puter is located in this vehicle. it has running problems that cant be explained,it is running at fast idle when started and when it stalls at idle the service engine light is flashing when that happens. also it periodically just cuts off while driving. please help me!:banghead:

I think 93's were still under the dash on the passenger side.

thanks,i'll check it out as soon as i can get to it
