Any videos or write ups with some really nice pictures to go by that I can work off of?

the reading that I've done so far has not been very encouraging. Sounds like it can be a ghost that cant be found in some...and I sure hope mine isnt one of those

 

The truck is a 94 with a 22re btw. I can find pigtails for a 6 cylinder, but not much for a 22re. The sensors appear to be fairly expensive as I see too.
