ok so i have found the wire goes into the fuse block and connects to the #18 fuse labeled emmisions and aux fuel tank per haynes manual. problem is it states that this wire comes from the ignition, not under the hood. im hoping someone has some kind of insight on this.

i wanted to update so no anyone else having this issue can find it. the wire in question goes into the plug as a red wire with light green stripe. out of the plug it is a black wire with purple stripe. this wire goes to the harness and ties into a splice for the coil. i found a truck in the pick apart with half the harness and was able to narrow down this. now all i need to do is figure out how the truck is pulling power when this wire isnt hooked up. seems to be crossed over to the start solenoid.
