NA2t stuff vacuum pump, egt, oil temp etc

alright guys, i am doing an na2t swap in my 86 and have a vaccum pump here along with a 1991 m30 upper intake mani with an EGT sensor on it.
i ordered a SLC PP2 wideband and have installed a nistune onto my ECU.

First thing on my to do list is to install a vacuum pump, i have the canister from a turbo as well.
How would i go about wiring this pump in? what does it wire in to?

Second thing, how would i wire this factory knock sensor into my harness?
anyone know where to get ecu pins?

Same thing with the oil temp sensor, where does it go?

Does anyone out there run an EGT on their z31? if so, what does it run to?

Ive also been looking into the hayden oil coolers, but havent found any decent reviews on the common 459 unit that seems to be common on z31s.
I do have a check valve on my block for the oil filter, do the haydens come with them or does it matter since they are thermostatically controlled?

There is a lot i need to do, ill update the thread as i come across things.
thanks!
