not to be a Dingleberry but I recently deleted my AC/Heater and in doing so learned that the only way to get the AC/Heater wiring harness out is to have to cut that pesky brown wire that disappears into the main wiring harness under the dash, everything else unplugged nicely, were you able to unplug yours somehow?

Brown wire does not have to be cut. There is a small metal tang on the female end of the wire connector. Use a small flat blade screw driver to depress this tang inside the plastic plug then the uncut wire can be pushed out of the plug. To reinstall, pry the metal tang back out and simply push wire into plug until it clicks.

Is this from a 69 - 70 or 71 - 72? I believe they are different. I'm looking for a 71 - 72 style. Thanks

Wiring removed from a 1972 truck.
