couple more questions.

harness is from a 1988 4.3 manual truck. I'm down to the last couple of things.

The blue wire coming off the ESC at terminal E:

is cut on my harness. do I need a knock sensor? can I bypass it if I need it or will it run regardless as I will need to harvest a plug from the u-pull which will be a bit before I can get back there.

second, I think this two prong plug with a pink/black wire and a cut (either brown or gray, I honestly cant really tell it seems to change in the lighting) is for the EAC solenoid. the brown wire is cut so no clue. I will try to finish ohm'ing the pink/black wire tomorrow as well. just seeing if anyone recognizes this plug. If it is the EAC, what is this sensor? do I need it? can I leave it out? I cant even find a pic of this thing online lol.

next, the fuel pump relay...again....I cant figure out what happens with the red/white strip wire? no clue as it is cut. I believe its the same as the "red" wire here though?:

the one coming from terminal C of the fuel pump relay in the diagram that goes I think to ALDL terminal "G"?? is this correct? If so, it looks kinda off but at the same time I'm really not sure how to read this relay diagram (I did not mess with the wiring to it though just fyi). when I look at the back of this thing as opposed to the front, it looks like the red/white is coming from terminal D? ugh.

and finally, a pic of my mocked up mess that is hopefully about ready to test fire (59 chevy 235 inline-6):
