Trying to get the A/C Working

[GT400]

Been a long time since I've been on the forums! I'm now old and tired of being sweaty all the time just to drive my toy, and have been trying to get the A/C Working again. I've got the lines plumbed up, just trying to figure out the best way to wire it up to retain the original auto climate controls. If anyone has done this succesfully, it would save me some time pouring over wiring diagrams.

1991 Supra 7MGTE (originally)
1992 Sc400 1UZFE & ECU (installed forever ago)

Thanks
