The 66 solenoid mounts to the shroud on the left side, over those three 
dimples. The 65 solenoid mounts to the condenser mounting bracket. 
Different parts.

Adjust idle with the A/C off, using the carb screws like you would on a 
non-A/C car, especially SINCE YOU SHOULD NOT RUN the A/C with the engine 
lid open. You WILL bust a hose due to high head pressure. This is why GM 
installed a mercury switch on the engine lid for 66 and 67 firewall 
mounted condenser models. Sorry for the shouting, but I have seen hoses 
rupture from people doing this. Very exciting!

If the idle does not remain the same compressor on to compressor of, 
then adjust the rod to match speeds. Or at least adjust rod to keep 
engine from stalling at idle with the compressor on.

It is possible to mount two relays under the dash to remove the heavy 
current through the rare and prone to failure A/C fan switch, without 
modifying ANY factory wiring. I just have to remember what I did!

I am replacing the carbs and looking for a gas leak somewhere under the front. The condenser is the 1966 style, up on the firewall, so I am wondering if there was a '65 mid-year change? Everything else indicates it is not an add-on.

I also can not find how it is adjusted in the shop manuals as there are only drawings of the solenoid. I assume it is adjusted by turning the activating rod in or out when activated??? The instructions only say to adjust the idle to 550.
