Also #18 in the upper hose nozzle? Apparently '96 still has the fan timer module with 2 fan switches. I think that other one has a different setpoint & it's active after you turn off the engine.

Thats exactly the problem. The car will continue to run the fan for probubly 5 minutes after the car has been shut off. It's not overheating by anymeans. So which switch is what?

Both fan switches are wired into the timer module & it wasn't clear from the drawing what kind of logic was going on inside the timer. But I think it's either #18 or it's both together.
Check both of those switches for continuity between the 2 contacts. When it's cold, I think they should be open. Probably one of those is stuck closed, which would run the fan 'forever'; but the timer module (correctly) shuts it off after a few minutes.
On that picture #10 looks like just a hose nozzle. I suppose the fan timer module is in one of the fuseboxes, it'll look like a relay. But it's a separate component from the fan relays.
Just for grins, #19 is the temperature sensor for the ECU, #15 is the sender for the dashboard temperature gauge. #16 & #17 are both fan switches, you'll have one or the other depending on what model. Honda shares those pictures among several versions of the car.
