I posted this in the touring section as well, hoping for a reply.

Changing the front brake lines on my 2010 Road King. No issues from the ABS module forward except of the connector that is mounted under the triple trees. The one on my King is really oxidized (don't know where this bike was kept before I picked up as project) and I can't tell what is needed to remove the connecting bolt. It appears to be a Torx (hate Torx) but I can't get a size determination. A T40 seems to sit in the slots but has some slack. A T45 is too big. It does not appear that any Allen heads fit it. I also don't see it in the manual. Any ideas on the size of this bolt?

With it being oxidized, I may only get one shot at it, even then it may round.
