To start off i have a 2005 automatic civic. a 2003 manual harness for a civic and a k20z1 with the engine harness

like the title says i need help with a bunch of wiring i have a vss wire from my 2003 civic harness (from c101)*but the *2005 rsx harness doesnt seem to have one in the c101 plug. what do i do with it.

also theres a light blue wire in my civics c101 plug but i cant seem to find what it does.

my last concern is that my rsx does not have white air fuel ratio sensor wire in the c101 but it has the other three. how would i go about wiring my o2 sensor?

Thanks so much for taking the time to read this. Im sorry for the amount of questions .
