Default ERA temperature sender questions

Hey guys. I just received my new dual-plane Blue Thunder intake. Really nice piece, high-quality.

At any rate, my old Victor intake had a 1/2" NPT threaded hold for the temperature sender, and the new one has a 3/8" NPT. The sender that comes from ERA has an 1/2" NPT reducer that fit into the old intake, and the sender itself is threaded with some sort of smaller thread that fits inside the reducer. The smaller thread sort of looks like 3/8" NPT, but it isn't. It's slightly smaller, and I can't tell what it is.

So my choices are: (1) Get a 1/2" female to 3/8" male NPT reducer, which is bulky and ugly, (2) Figure out what the smaller thread on my sender is, and try to find an adapter, or (3) Try a new 3/8" NPT sender, which most seem to be.

So my questions are:
- Does anyone know what the smaller thread on the sender *could* be, if it's not 3/8" NPT and not AN? It's slightly smaller than 3/8" NPT.
- The sender is soldered on to a thicker wire. Can I replace it with a more standard 3/8" sender, and just use a spade connector on the wire I have? Or does it work differently?
