ka24de obdI crank sensor myth vs fact?

[HapaxLegomonon]

So on my 95 s14 I'm getting a crank sensor code.*Here's the deal:

1. I keep seeing post of ppl arguing rather or not the obdI crank sensor is in the dizzy or not. Is it that crank and cam sensor are the same thing? Or, I see two different codes in the book for crank sensors and is there another location for a second sensor which is not on the trans bell housing but mounted near the starter? When I look up parts, I keeps seeing the same one which mounts to the bell housing on later models for mine but I keep seeing ppl say that it's nonexistent on 95 and earlier ka's.

Can somebody straighten this out for me? I need facts, not assumptions.

I will dismount the starter my self and check soon enough when I change my mounts this week. However, if there are two crank sensors, which code goes to the dizzy, which goes to the other? There's about a $200-$250 price difference in the dizzy replacement vs the sensor I keep seeing when I do a parts search.

2. I keep seeing ppl saying that the crank sensor only detects a misfire however, I'm not getting any misfire code, only code 82 for the crank sensor aaand I read a sensor guid which states specifically that bad crank sensor does in fact create a misfire. When I clear everything, my random misfire goes away but once the misfire comes back, still no code for that, only for the crank sensor, code 82, not the other crank code.

Who's got real facts? I keep getting running upon contadictory answers in other ppls threads so I created an account specifically for this question. It'd be nice to clear the air on this.
