Default Help me wire up A/C after swap....

The car is a 2000 RS. The A/C components should be fine, they're the original from before the swap. The engine/ECU/wiring are all EJ20K.

I need to figure out how to wire up the A/C properly. I've got the USDM and JDM wiring diagrams but because the donor car uses a different climate control than the RS one, it's not quite "plug and play".

Mainly it's how to wire the evaporator thermoswitch that has me puzzled. The A/C on switch is also wired differently between the two cars and the JDM one has a couple of extra components that I'm not sure I need.

If anyone has done this swap previously with working A/C, please point me in the right direction. Thanks in advance.
