I am finally getting around to installing the new wiring harness on my 1937 120 and would like to know if anyone out there can lead me to any documentation that specifies the routing of the harness through the body and the attach points of same. I do know that the tail light / fuel gauge portion runs down the passenger side within the chassis, but the portion that inhabits the passenger compartment itself is a mystery to me. I cannot seem to locate any information on any web site that can show me the routing and / or attachment of the harness.
Thanks for any information you might be able to give.

I don't think you are going to find anything regarding wiring with that much detail unless possibly flackmaster worked up something to supply with his repro harnesses. The factory wiring diagrams are laid out more or less in a birds eye view and you can get an overall idea of routing to where things are but details of specific clamps and holes are not going to be shown.

IMO, the best thing would be if an owner would take a few photos of his car showing under the dash and post them for you but barring that the next best will be the factory wiring diagram.

Runs down the drivers side not passengers.

Thanks. I'll look at it there and see how it fits.

Wiring harness sits on top of frame on driver side in engine compartment Feeds generator front head lights starter then goes up edge of firewall and enters into inside of car The wires to the regulator come off of this main feed along edge of firewall The wires to the back run along driver side of frame Horn wire is fed from starter selonoid

Here's a picture of split at firewall

Here are two photos that may help you get it done. One from under the dash looking up on the drivers side at the harness holder or guide and another looking down at the drivers side harness holder or guide.
