This is a feature unique to 71. There are two relays under the dash between the glove box and the firewall. They work together to apply power to the compressor clutch for a few seconds after turning off the engine. The load was intended to help kill the engine. Engine run-on or dieseling was a problem on the detuned early smog engines starting in 71. 72 and later used an idle solenoid. If a 71 had an automatic trans and no A/C it may of had an idle soleniod, I don't know for sure.

If the clutch stays energized you have a problem. You can remove the relays and install a single jumper for normal operation of the compressor clutch.
