How remove wiring plugs from firewall
 

Starting to clean up the firewall during my cab off restoration. Is there a trick to removing these successfully? I've attempted to force the softer rubber around the outer most edge back through the hole but it doesn't have a whole lot of give to it. Help?

The ignition wire plug has a bevel to it you need to push the harness inside towards the glovebox first then pry out the grommet. The heater wire grommet should not be that difficult to push out.

ah... so they are two pieces? Does the grommet come off from the inside or the out?

I'm over 50, cant remember. If memory serves me towards the inside of the cab.

Just pulled mine out last week. The plugs are held in with semi-hard rubber grommets. I pushed the edges in from outside to inside and worked around the entire edge before it pushed through. It seemed as though the plug was going to break or get damaged, but it just took a little effort and working around the entire edge. Used a flat head screw driver to do the deed. Hope that helps somewhat

Man they are a lot tougher than I thought... put the one on the passenger felt like the entire thing was hard plastic.... I ended up hand sanding around it and taping it off - not wanting to break it off.

if you can heat them up they become pliable. to put them back just give them a little microwave time

...and if we use only a microwave, will male chauvinists still call us a sissy?...
Good tip, btw!

I have found that sometimes a little silicone spray helps make them slippery enough to get them out of the firewall.
