how to get wire harness through the fire wall of 2001 blazer

I see the boot, will check into it in the morning, thanks for the help Jim

Jim that boot just plugs the hole, solid 2 inch wire bundle goes straight through.

Keep the boot and use it to seal the hole in the Jeep. If the hole is big enough in the Chevy the whole thing could fit through without a plug but I would think there is a plug.

Inside the fire wall the wire bundles branch off in all directions and are as stiff as a steel cable, goning to dump this motor and trans. and find a prefeulinjected engine that I can do something with, sic of all the wires

No connection at the fire wall, I cut a large hole in the firewall but with out cutting off all the tape and loosening the wires no way of getting them out, thanks for trying guys
