Wiring harness grommets

[AZ73]

I have these 6 grommets for the wiring harness. I contacted painless to see where they went and they were less than helpful. I thought maybe #1 were for the rear tail lights, but they seem too big to fit into the hole in the body, and for the connectors to fit through. I think #2 is for the main harness through the firewall on left and right side but want to be sure. #3-4 I have no idea. Any help would be appreciated

#2 looks like the rear tail light post grommets.

1 is for the firewall connection depending on the year. 3 and 4 might be earlier year firewall as well. 2 looks like the rear turn signal (thats where i used them and they fit.

Thanks guys. After reading your comments I remembered I still had the old harness someplace and dug around the garage. The funnel shape is indeed for the firewall wiring harness. Funny, Dennis Carpenter has it listed for an antenna lead.

Several vendors sell #4 for the tail light and the painless kit only included one. Northeast Classics lists #3 as Air conditioning hose or wire harness grommet. #2 looks looks like just another option for firewall harness.
