so long story short, the cables that supply power to the ignition key switch wont carry a load. can anyone think of why this would just suddenly happen, i think there has to be a relay somewhere but i cant find it. im wondering if its possible for there to be one IN the PCM, quite honestly if anyone has any type of knowledge on this or wiring diagrams that are directly related i might be able to run it with out hot wiring it

Not quite sure what you're asking. What is or is not happening?

okay... when i stuck the key in the ignition and turned it, nothing happend, no gauges no start. after hours of testing stuff we figured out that the two wires that supply power to the ignition key switch wasnt doing what they where supposed to do. we tested them, and it has 12 volts but when we turn the key it drops to nothing. which leads me to belive that there is a relay somewhere (because this was a very sudden issue)

so what i am trying to figure out is "where is that relay"?

The first thing I would check would be grounds.ground a test lead to the steering shaft or around he switch.When thing get stupid in electrical I find that a ground is to blame.
Good luck
