Hey guys i have 2 connctions on a 90 350 TBI truck motor that i cannot figure out, i will attach the pics of them. Also the gray wire that comes out of the Fuel Pump Relay, what did you connect it to?
Can anybody identify these TBI connections?

Here is the other pic.
They look like the EST module and knock sensor connectors to me. I can run the wire colors if you'd like.

have the knock sensor already hooked up with the right wire, the circular plug comes out of the big 6 wire plug i am also holding in the picture, the 6 plug connector had 2 wires that went to the bulkhead connector! Yea if you wouldn't mind checking i cant find them on my diagrams.
I just looked at my EST module and that ain't it either. I'll have a student run the electrical diagram this morning.
