Icon9 Check Engine Light (CEL) does not turn on... EVER!

Hey guys,

So I've done a lot of research on this so you can assume I am not an idiot like I've seen in countless threads.

1992 Honda Prelude Si 2.3L H23a
OBDI!!!

Problem:
Anyways, my Check Engine Light or Malfunction Indicator Lamp (as referred in the repair manual) never turns on. Nor have I ever seen it on. The light is supposed to turn on whenever you first turn your key to start the car. All the other lights light up, except for the CEL. No error codes shoot out obviously (or non that I can see). Unless you think my car has been in factory, tip top shape and has no reason to shoot out an error code, you are gravely mistaken.

Attempted Solutions That Failed:
1. Tried shorting the Service Check Connector (2P). Nothings happens. (OBDI by the way)
2. I have reset the ECU countless times. Nothing happens.
2. I have disconnected the battery as well. Nothing happens.
3. I replaced the bulb with one in working condition (used the bulb right next to it and put it in its place). Nothing happens.

Repair Manual:
I've read through the repair manual and its flow charts on diagnosing a bad ECU but that requires a test harness of which everyone has trouble obtaining. Has anyone had this problem and figured out a way to diagnose a bad ECU without the test harness? If not, I guess I will have to try my best to find a known working ECU and replace. Lemme know your thoughts, Forum.

P.S. The car is runs totally fine. It would be so nice to have error codes to diagnose car problems rather than doing the old school way of diagnosing symptoms.
