Car is a 1975 and I am going back to the OEM steering wheel from a Momo. I bought a steering wheel listed for a 1975 car, but it didn't come with the horn pin. I see there are two types, long and short with each saying they fit a 1975 1.8 car. How do I know which is correct for the steering wheel I have?

Short.

Long.

@mepstein Can you clarify, so the 72 to 76 914-4s don't need a pin at all, since the brown wire takes care of that function? In the PET for those years there is no pin shown at all, so that would make sense.
Thanks in advance for the education.

As mepstein said the difference is the slip ring.

#4 is the slip ring, it replaces the pin. The brown wire (ground) connects to the batwing which completes the circuit to ground when the batwing contacts the slip ring.
The horn has power all the time, when the circuit is complete to ground the horn operates.
