TLDR summery:
For everyone's information and in case it has never been said here before, here is where I wound up getting the pigtail for the four pin connector on the distributor.
http://www.ebay.com/itm/321...e=STRK%3AMEBIDX%3AITBrand and part number listing: PartsMaster 84072. It says that it doesn't fit the Fiero, but that is a lie, it is currently installed and working just fine in my 1988 GT V6.
Other part numbers on pigtails listed that it also can work are listed as follows: SMP S551, Pico 5602C (5602PT), ACDelco/GM PT757, 12126487.
To recap on all the pigtails I needed and ordered are:
Oil Pressure Sending unit:
General Motors PN: 12085499Manifold Air Temp Sensor (that two pin sensor after the air filter):
General Motors PN: 12102620Distributor ignition module? (4 pin connector that plugs into distributor):
PartsMaster PN: 84072As I go through my car and fix random things Ill add more harness part numbers as they come up. If anyone else has any they would like to add feel free!!!
