Got Sick of the Beep-Beep

[magwakeenercew2jh]

I've been playing with the grounding on my home-fabbed horn ring for too long now. Yesterday was the "final straw". I got P.O.'d at one of the neighbors (a few acres away)
for a "sustained" breaking of the country-quiet. Seemed he was running a chain saw or something for an almost unbearable amount of time.

Being a good neighbor, and understanding that *someone* has to work, I went outside to see the direction it was coming from. Not that I was going to get strange...
I just wanted to see where the noise was blurping from.

Okay....It was from under the hood of my truck. I have no idea why...Something to do with my insulating the horn ring with something that didn't like the heat...
Got (ambient temp.) hot and started it's infernal grounding again.

Point: I'm moving the black wire to a "tasteful" intermittent grounding button near the dash. And I don't want to cut the black wire that goes to the plug for the horn relay...
because one day when the weather is good, and all the stars align, I'll get back on it to re-plumb it to the horn ring.

But for now, I'm wondering if there's a way to release the one terminal from in this connector without going at it with side cutters and screwing up the plastic housing that holds the red/green/black
connections in the plug? I already put a small screwdriver in there and tried to "finesse it" around. This is a brand new M & H wiring harness, so I hate to start mooshing stuff up
My normal approach would be "cut, solder, shrink wrap, and be done with it".....But, as I said, I'm trying to NOT cut the black wire, and simply replace it with another black
ground wire directly to the new horn button.
