Nope!
I ended up ripping the boot down the side.
Had it all the way in to the last rubber collar, after working at it for an hour.
That last pull like the video showed and i pulled one wire all the way through.
That may work on the bigger housing, but not the little Dart.
Well, the boot is now going to get some superglue and a seam!!
I got some flexible glue too.
