So updates:
It was still acting up, so last weekend I finally got around to upgrading the distributor. Wow the car runs better, most notably at low rpm and when cold. However it still decided to act up, yesterday i decided to finally put the other ECU in, i was hesitant because it was from an older car that had its battery hooked up backwards once, but when i ripped it out it turned out to be nissan remanufactured (who knows from when) I stuck it in and it works great, seems to run the engine differently than the original ECU which is odd, but its improvements rather than faults, i have plans to replace the alternator soon but will wait to see what the new ECU does first.
As for the heater it seems to be its own issue thst just has bad timing, i kind of think its the temp sensor in the blower housing it sits in going. Turn signals I am unsure, its too rare to diagnose, and too inspecific, someone needs to stop feeding my car after midnight.
