Was removed over year ago by some body else n vehicle scrappped
i purchased new o2 sensors.
The harness was hacked off at drivers side valve cover..
wired in new o2 sensor pig tails. And evap pigtails..
now the harness has 5 plugs in total.
the ecu has 4 plug spots
only 3 of the 5 plugs fit into Ecu
used the r150 tranny from 3.0l

The other two plugs for your ECU come from the body connectors. That's where your power, speed sensor, and several other things plug into the ECU. Unfortunately, those connectors were probably scrapped along with the rest of the car. You can buy them from a dealership or you can try to find them from the original manufacturer, which was probably Tyco or Amphenol.
If you haven't already figured it out, the driver's side connectors you're probably missing are the VPS sensor and VSV, the oil pressure sensor, and the crankshaft position sensor (IIRC). You can probably start the engine without these, but it is a REALLY bad idea to run an engine without a working oil pressure sensor.
