Hi everyone,
My son and I are trying to wire in the ignition switch for our 1950 Chevy 3600 truck.
We have some discrepancies here that you guys may be able to help us figure out.
We have identified the terminals according to the pictorial shown. "A" is at the top left. "I" top right. "B" bottom (in regards to the Y shaped embossment).

Now looking at the old ignition switch (photo shown). The thick red battery line wire appears to HAVE BEEN connected to the A terminal, not the bottom B terminal, where we think it should be.

Was it correct before, or do we have the right idea now?
Now that I think of it, the original switch didn't work (hence why we're replacing it) and also, if I recall correctly, the old thick red battery wire was a little "crispy".

Thanks in advance.

Old ignition switch for comparison. Taped terminal is where the red battery wire went previously.
