Personally I think that clip is total overkill. I've never even put a spare into my parts case because you never lose or hurt it. The wiring harness is much easier to hurt than the clip. Be gentle and use a small screwdriver to help get the clips up over the tab and you should be fine. No doubt Greg replaced the harness when he built it. That's my $0.02 though.

Add on a jug of Dave's secret sauce aka drive train fluid and order 5 less quarts of Amsoil.

You'll be staring the 4th clutches and it's hub in the face, otherwise, there's very little you need to be concerned with unless you pull it and do the clutches.
