HellaSexyS13

so im almost done wiring in my s14 sr20 into my s13 coupe with a few connectors i dont know what they are for or if i need them. i got the harnesses from wiring specialties so everything is correct, i contacted them too for help and still waiting to here back so im posting on here too.

in picture one it shows the trans harness and a plug on the trans that i circled but none of those connectors i have fits in it. i know not all the plugs on the trans harness are used but i cant find one to go into the one plug on the trans itself. here is the pic:


picture 3 shows three connectors in the front passenger side coming the from the fuse box are and i dont know what they were for or if i need them for the swap or not:


picture 4 are 2 connectors on the drivers side, one looks like a vacuum hose goes on it which im guessing is for the one on the trans and i dont know about the other:


and the last pic is this wiring and plug comin from the power steering line, what does or did this plug into and do i still need it:


thanks for any help
