I agree pictures would be great but since I never had these connectors I can't help. I first became aware of them during my '37 restoration when I received my wiring harness from Rhode Island Wiring. Attached is an image of part of the main wiring harness drawing showing the connectors. Note that it says to reuse your original connectors since no one reproduces them. I have included detail from the drawing which may help Chasz if he can discern the colors of his original wires. This shows gauge of the wire and factory color (YxR for example means yellow wire with red cross hatching). I have included pictures of the interior of a headlight bucket which shows where the female part of the connector would be attached. The other photo is of the exterior of the bucket where the male part of the connector would be inserted (the part shown in the photo at the beginning of this thread). That hole is about 7/8 inch diameter so the connector is large, at least 3/4 inch diameter. The 1937 truck has no terminal block like Tiny's picture shows.

If you search Ebay for vintage headlight connectors you get a variety of examples of one, two and three wire connectors for different manufacturers. I understand Ford Model A used something similar. The advantage of such a connector would be rapid connection on the assembly line. I assume problems later on resulted in GM going to the terminal block on the inner fender that many of us are familiar with.
