Rewiring my '34. Anyone know the correct routing for the cowl lamp harness? One end connects to the lighting harness near the light switch at the bottom end of the horn rod, and the other 2 ends go to the cowl lamp pigtail harnesses on either side inside the cab near the windshield mounts. But where does it go thru the firewall? Thru the hole with the main harness (along with the wiper hose and temp gauge tube and gas gauge tube)? I can't remember seeing any photos that show 2 harnesses going thru the firewall there.

Ok, so I tried several routing options. Going thru the main harness hole in the firewall looked ok but didn't work, the cowl harness was about a foot too short to make it to the pigtail at the front of the light switch. Same problem when I ran it under the floorboard by the pedals. The only solution was to run it thru the speedometer cable grommet. Doesn't look too bad as it's pretty much hidden by the cable. Don't know if that's the 'correct' routing but it gets the job done.
