Did mine slightly differently. After I removed the EPR valve in my compressor I added an adjustable clutch cycling switch. Mounted it on a brace behind the glove box. Think it had an 18" long capillary tube on that particular model. Drilled a tiny hole (with a rubber grommet) in the ac/ heater box to put it's end in between the fins in the evaporator and wired the under dash a/c clutch wire in series to it. This switch has two adjustments. Cut in and cut out. Stuck a digital thermometer in the center a/c vent and set it at I think 34 degrees cut off and 40 degrees cut in. With a big block I really don't notice much of a RPM drop when it cycles. With a 225-6 probably more so unless there was an idle speed solenoid to up the rpm's when engaged. It doesn't start to get as cool initially as my 93 Taurus, but it gets way colder a short time soon and I'm turning it down to the low fan speed 5 minutes into my 10 minute drive home from work. This link prompted me to remove the EPR valve for improved cooling: https://www.forbbodiesonly.com/moparforum/threads/ac-compressor-oil.147951/page-2
Yea it has to get the heater core antifreeze cold but man after it does that old V2 will freeze you out!
