Oh yeah from the information i gathered, It seems as if some people told me the "2 prong" connector should get spliced into the Obd1 thermostate housing sensor, Then what do i do with the orgional OBD0 ECT sensor?

You screwed up, the ECT sensor is in the same place as it was on the original motor. The only change is the fan switch, which used to be on the back of the block (2 male pegs) and it is now on the thermostat housing (2 pin plug, same plug style as the IAT and ECT).

So basically i need to find that green plug again, as it should still be in the back of the block, and run the fan switch with the 2 prong onto the thermostat housing? So basically converting the 2 prong thingy into a green plug correct?

Yes, you need to find a connector that fits on the ECT and run your old ECT sensor wires to the new connector. It does not matter what side ( or order) you put the wires in. All the ECT sensor does it gives the cooling fan ground.

Hey uhh took a long and hard look at the back of my block today.. there is NO Engine oil temperature sensor on the back! My motor is a 93 so i'm guessing its the same like a 94- up LS, cuz they only have the oil pressure sender in the back like mine..
