Pulled the engine last year, and now reinstalling it, but can't figure out what these are for?
I removed the AC a few years back and didn't remove the connectors, but does the AC take these 4 plugs? I have the fan plug, drier plug, and 1 compressor plug pulled to the side not included in this pic. Same with the radiator, and cooling fan

They are on the front of the engine, under the intake manifold. Everything around the throttle body is plugged in, as is the starter and alternator.

What are these?

Starter harness and knock sensor.

knock is already plugged in, and starter has the electrical cable and ground connected, but don't see where any other connectors go.

Does this help?

Yes, a big help... But what does "Starter Solenoid (to engine harness)" and "Alternator (to engine harness)" mean. Neither the alternator or starter have plugs/connectors for these, so not sure where they go.

Do they go into one another?

Starter solenoid - letter B connector here:

I got it. The "to engine harness" connectors go to the engine harness connectors. So the 4 that I was holding plug into one another.
