Rb20 wiring woes

[ddtrav2]

For dohc s13 how to keep defroster wire on the interior brown plug?

For dohc s13 should I wire the power steering pressure sensor plug to the Rb20 pressure sensor switch?

To keep the a/c I should wire the a/c relay for Rb20 to the relay wire on gray plug but what about the Rb20 a/c switch. Does it get wired to the ambient wire?

I want the Rb20 ecu to turn on electric fans automatically. I wired the fans to s13 condenser. Can I run the wire to ecu in which the ecu signals the fans to come on or does the Rb20 use the condenser fans strictly for a/c.

Also does anybody have a complete pinout for the dohc brown interior dash plug or know where to find one?
