1994 Pathfinder 4x4 Automatic loss of power

Hi i was recently installing a new cd deck and ended up short circuiting the E-AT power switch or component that it is hooked up too that switch.   So now when i push on the gas pedal there is a very noticable lac of power.  I've checked all the normal fuses in the little case, and i'm wondering if there is another fuse somewhere else that i'm missing,  or if i shorted a sensor or something like that.  Some help would be greatly appreciated.
