I was going through some old notes today, and I found something from Scott that might be helpful. My system isn't charged, plus its single digits here so I can not test at the moment.
The A/C temp switch that the 185 had in the water neck is not available on the 205 neck.
So there were two options noted there for making the AC work.
1) tapping the water neck and adding the 185 sensor, which retains the safety system if you over heat.
2) Close the switch for this wire.
It is normally closed and opens if the engine is over heating. So if you ground it, you remove the saftey feature but it should allow the AC to turn on.
If anyone wants to try it, keep us posted. If not, I will see if I can trip my pressure switch and try it when its warm.
