hey guys ive got a wolf 3d v4plus which im wiring to a ecu plug so its a plugin type thing, now ive got a few wires that im unsure on,

pin 10 compressor clutch engaged and pin 41 is ac clutch - whats the go with that?
pin 39 intake air temp - i didnt think the i6's came with this?
pin 58 vehicle speed sensor - this wont be needed with the wolf?
pin 17, 42, 68 and 46 and electric drive fan 1, 2, 3 and 4 respectively - are these thermos? if so why are there 4? is it 2 speeds per fan? if so which is high and which is low for which fan?
pin 69 ac relay - again would this just go into the ac clutch wiring or is it some thing else?
pin 86 blower fan speed - this wont be needed with the wolf 3d?
pin 89, 90 and 91 are TPS, voltage reference and signal return - are these wires for the TPS?

also, there is a black wire with a white trace from the knock sensor, map sensor, coolant temp sensor, tps etc, are these all earths? does it matter where they are earthed? or do i need to run extra wires?
any help would be appreciated thanks
