Just did my S14 yesterday
hammered part of the lip for added clearance
removed one of the plastic harness holders
freed the harness
cleaned the metal and attached sticky zip-tie-holding fasteners
re-taped harness and put it in place
hammered the taped harness so that it would sit more flat
not so sure how well it'll work
but I'm not planning to slam the car
if it still rubs then I'll just relocate the harness to the engine bay.
