ls1 harness how to protect the wires

[ACII]

Hy all

GM is originally using a corrugated tube for protecting the wires.

Sorry but i am not sure how u call it in english.....i mean those black flexibel plastice tubes...
My english translater calls it "corrugated tube"

So after i have stripped the harness....i want to use the same tube, but i am just wondering if the sharp edge (where the tube is slotted) wont hurt the where the cables come out of the harness.... ???

Of course i have tapped the cables before i put it in the tubes... but i guess of all the vibratons of the engine the sharp edge will cut it through...

I hope u understand what i mean !! :-)

Thanks for ur help
