Nissan Silvia PS13 Wiring Diagram

I have a 1992 Silvia SR20 5 speed that had the wiring harness cut up and peices stolen before i brought it. I have the electronic climate controll unit for it, but the wiring diagrams i have been able to aquire only have the manual version, or are for the S14 with climate controll, which appears to be different. Have had the fan working, and temp selection but not the venting positions. Any help would be greatly appreciated.
