So here is the first plug:

back of plug:

what is this and where do I connect it to? The diaphram type black thing missing a hose.

Is this how you jump the harness so it will swap? I dont have the 3 plugs under it connected. Did a 5 speed swap from 96 to a 95 shell with no engine bay wiring left except from fuse box.

and what is this 3 wire plug for? has a thick black wire with yellow? stripe and then (2) yellow with green stripe wires? ends about where the fuse box is.
