Positive update, i went digging through the electrical rats nest that the previous owner turned the wiring by the fuse box into, when I found out that when I moved the harness, i could hear the fuel pump waivering, i chased the connection back to where the FP ties in, and they had used a funky connecter where you strip the end of one wire, the middle of a live line, set them next to eachother, then fold a strip of metal across them both, and its all encased in a little box which I had previously thought was a fuse or resister. So i tore that out and properly sodered it, as well as all the other wires that had been connected like that, and one with a small twist connection that was coming apart, suddenly the fuel pump does not waver when moving the harness, and my turn signals work again.
I have no idea which systems I effected while under there, however my car has had no running issues since then (though it has only been a short time so far), I hope it serves as a warning to those to always properly wire electrical systems, with solder, because it can cause nightmare to diagnose intermittent failures for you later on, or the next poor person who has the car.
