Just bought a 31 roadster- Questions 1 at a time

[31deluxe]

Picked up this 31 Roadster just before the winter and have not had much time in the New York unheated garage to play around.
Do you think I need a new wiring harness or just a little electrical tape.
Someone did a nice job of brazing the fan. Can you see it?


Seriously. Reading a lot of posts on how to upgrade headlight wiring using bullet connectors.

I will be using bullet ends on headlight bulb socket end and from new headlight wiring harness.
If the spring connectors are removed or not used on the bucket side where the conduit connects to the bucket. What puts tension on the conduit connector to hold it it place? Seems that the dimple on the conduit ferrule would not be enough to hold it in place.
