I've found others who have run into this problem so I figure I'll just put it out there:
Removing or installng the nut on the distribution block terminal can VERY EASILY crack the distribution box housing. The threaded terminal has a square end mounted to the plastic box to keep the terminal from spinning. IMO bad design because that square end is only kept in place by plastic ridges on two sides. When tightening or untightening the nut the square end of the terminal has a habit of breaking the plastic ridges and then spinning freely.
The seven year old plastic in the hot engine compartment has a tendency to be brittle. Use a penetrant/lubricant on the terminal stem and DON'T put much pressure wrenching it or you will break it.
I broke mine loose not knowing how fragile the setup is. Luckily, I took my time and got the connection put back together snugly and it's working fine. I also luckily found a good dist. box and wiring harness on ebay as a back up in case I have an issue with it in the future!
