Default 1962 engine harness routing

Does anybody have pics available of where the engine harness goes through the firewall? Also I'm assuming there is some kind of grommet that goes there, is this available?

I am under the impression there is no separate engine harness, as it is all a part of the fuse block.

Assuming it's the same as 1961, there is no separate harness, the wires all pass through the firewall on their way to the fuse block, dash switches, etc. The hole in the firewall is on the driver's side, adjacent to the brake master cylinder.

Checking my 1961 parts catalog, I found p/n 537153 for "grommet, main wire harness thru dash." According to the PY online parts lookup database, that part number is good for 1961 to 1963 full size Pontiacs. I don't know if anyone is reproducing it but you may be able to find someone who has a good used one, or a parts car that still has one.

Thanks, that helps, does anybody have a pic showing which hole on the firewall it goes through?

If I recall correctly the grommet has more than one hole in it for the wires to pass through, I think two or maybe three.
