TPS issue

[e5s4y]

So I'm hoping this is the last issue I have. I can NOT find a signal in the wires in order to get my tps set right. I tried at least a dozen different times and can't get it. I took it to a friend's place and he couldnt find the signal either. Checking resistance across the terminals of the tps checks out fine.

Probing the plug on the front (where it connects to the prongs on the tps) yields all the proper results (5v, ground, and signal. Or whatever it's supposed to be, it was right) but when it's plugged in, it's like the signal is gone.
Tried probing the back of the plug (afterwards read it was bad to do) tried sticking the probes through the plastic on the wires, even stripped some of the wire to have bare copper showing and still nothing. Anyone have any idea what's going on?

Only thing I can think to do right now is run new wires from the ecu and see if maybe thats an issue, but i would imagine that if the wires were an issue i would have a funky signal in the wires (which i dont when its not plugged in)

I'm sure this seems like im rambling, but im just trying to do my best to describe the issue. Ask some questions to clarify anything thats confusing.
