The guy who designed the electrical connector won, it is still there. I did come in second though, the wire is long enough that I got away with not disconnecting it; as a consolation prize it is a good place to hang the trouble light.
For anyone doing this job in the future I have a suggestion: In the book it says to put a 3/8ths bolt down to pull the plugs out from the top. That is what I did. The bolt went in quite smoothly. So smooth in-fact that the massey ferguson-er went right to the bottom and hung there. I grabbed my magnetic pickup tool but due to the placement of the tubes it was like you and a woman lying on your backs beside each-other and trying to have sex. After more tool and vocabulary building the bolt was retrieved. The lesson here is that putting a 7/16ths bolt down the hole gives far superior results.
Another thing to keep in mind is that the tube covers require a 1-1/4 flat wrench. The factory torque is 376,874.82 foot pounds, so have some heavy persuasion tools handy.
You will also need three 1/4x1-1/2 full thread bolts to do this job. Like me you are probably thinking "I have 10,000 of those, that is not a problem." But if you are like me you will have 9,999 of them that are not full thread.
