90 Where does this connector go?

[Corvette95]

Yeah, it's me on this 90 I bought. The PO had it worked on at multiple places for a no crank condition and they had all kinds of stuff wired into it, wiring connectors hanging etc. I am almost done with the wiring, I need help with where this ECM harness connector clips into. Can anyone help? Also, oil pressure is running high not out of range, is the instrument cluster pressure switch on the side of the oil filter housing? I assume that's why it is running high- when I finish this wiring I am going to tackle engine refinishing. Also, third brake light isn't working, I have not looked at it yet but from memory, I think there is a separate switch for the third light- that is next problem to tackle. (OP had vats bypass box of unknown origin - I removed that, starter wired into clutch with to a separate start button for when the key didn't work- ll that I clipped out and soldered the original wiring , including correct colors back in) - all done because of weak clutch switch- crazy! Thanks for all your help on this 90, I am sure more questions to come..anyway...here is the connector...
