Mark,

I always loosened the GP nut and then removed the GP with the nut and wire still on the GP. Then I removed the nut and wire after the GP was screwed out of the head. I then installed the wire and nut on the GP first before starting the GP in the head and tighte dthe GP nut after the GP was screwed tight in the head.

But now that I have ratchet box wrenches, I have to remove the GP nut first. So for GP installation, I cut the wire connector into a "spade lug" so I can put the nut on the GP first and slip on the connector after the GP is tight in the head. This is because the ratchet box wrench can't be used if the wire is on the GP.

The above was on a 116 engine. I haven't done any GP work on my 603 engine yet. Not really looking forward to it.
