I have a 1997 Nissan pickup and I was installing keyless entry. I have never done it before and I had it all working and as i was splicing into the red which is constant power ( I think) it hit the fram and sparked a little and the red wire got really hot! this red wire goes up toward the ignition ( i think). the keyless entry unit did not function properly after that when i hit the button and now the car will not start. What did i do and how can i fix it?

oh and i also checked the fuses under the dash and they all appeared to be good.

dose it go in to the on position and have you considered your trucks computer located underneath the bench seat passenger side
