AAR valve wiring connection - how do I disconnect?, looks stock, plastic box covering connection, afraid to "pull on it" Options

Happy New Year Everyone,

I am trying to do a bit of a refresh on my 1971, D-Jet stock car, (new vacuum hoses, valve adjustment, etc.) and I would like to pull out my AAR valve and inspect it closely (or replace with a known good one I have) but I am fearful on how to disconnect the AAR wire to the white wire. Its encased in what looks to be stock plastic rectangular wire cover, but figured I would ask for advice before I do any damage. Thanks in advance.

Best,
Reg

Oddly enough, I pulled my AAR this morning, that connector is a standard flat blade brass connector in the german plastic sleeve. Give it a shot of WD or Kroil and pull, it should come right apart. If you want to test the valve, put it on a bench and hook 12 volts to it. You should see the valve rotate and close in a few minutes. That will tell you if it's working. If it's not, Ian Karr has a great video that shows how to take it apart and repair it, if the heating coil is still intact.
Now I need to research how to check the Thermotime sending unit to find out if it's still good.
