Wire Through Firewall Grommet

How the heck do you get the power wire through this grommet? I electrical taped it to a hanger but I can’t get this thing through.

 

I poked a hole smaller than the cable, but big enough to get it started, then forced the cable through. It’s a tight seal.

 

I did exactly what yotabilly said

 

head to the grommet to the left a bit



Push a pick tool or long nail through, then when you see it inside, take a fresh razor and cut an X where it comes through.
