Have two connectors I’m not sure of their location any help would be great.

 

I wanna say that connector in the second picture either grounds to the oem manifold or trans.. IT's been such a long time. The first picture i already have two connectors connected 1) starter, 2) thermostat housing, Was there a 3rd spot?

 

okay the clip ground is the the oil pressure switch, now i need to find out what the eyelet is for.
