wiring harnes = bitch made!

we cant get our new turbo wiring harness through the firewall anyone know any tircks? i was told hanger plus tape plus pull equals success?
will this break off any of the connecting pieces?

probably if you pull too hard....try feeding it through one connector at a time.

that white piece that is around the hole pops out from the inside.if you already have it off i dont know i got mine through fine.feed it from the outside in.if your not already
