Dash electrical firewall grommt install

[Crazy Rusty]

I took my dash wiring out years ago when I started working on the burb. I went to put it back in tonight and realized the connector that fits in the hole has a hard rubber grommit around it. I think I might just try warming it up with my blower to make it a bit more maluable but I don't want to screw up the connections... any ideas of how I'm supposed to get that thing back in the hole?

Thanks!
