The connectors were easier to connect than they were to disconnect. I was told that's a good sign of a healthy connection: good contact & prevents moisture.
They do take some wiggling; it gave me a blister on my forefinger (though it completely dried up, without popping it, because my body dehydrated from the blistering summer heat today
My body needed all the water it can get!). 2 plier wrenches were needed. They were the original switches from '94. A good neighbor who works on his own cars helped me that one. Thanks to the both of you, & for your advice, leastonce. Cheers.
