My interpretation is to tuck it away so it's not flopping around
I recently removed that portion of my harness completely as I wasn't using any of the other components that tie into it. I have a heat backdate and running carbs. So no blower motor or WUR which are the other components that all connect. I was able to remove it and only snip the blue wire where it tied into the 14 pin connector to another wire that I needed to leave in the harness.
