I bet wire #2 goes to the other brake pressure sender/switch just like the visible one mounted to the bottom of the brake master

Like @Pighead said above for the #2 wire....

I wonder if the 40 had one of those under-hood carb cooling fans at some point?

Wire 3 and 4 look to be using a single slot connector. That type connector is what the temp sensor
on the manifold uses.

Here's a pic of the green connector properly hooked......and for the win...even the dual brake sensors hooked.
