This is a bit of tech I got of another forum.

First thing is you talk real nice to this thing

Get you fav lube for this job, dish washing liquid works good too

Find your 5/16" Allen wrench with a balled end

Run the boot over the wrench

Let it sit like this for about 30 seconds then take the boot off. Now you need to work quickly to get the wire through.
