98 Civic Ignition Timing

OK, my 95 Civic is a piece of cake to set the ignition timing, but my
daughter's 98 (east coast)Civic, is very confusing? And, I have read
multiple posts about shorting the connector and on the 98 there is only
one two wire connector imbedded in a rubber plug near the top of the ECU.
This 98 (maybe all 98's) is certified as meeting Federal and Calif
emissions standards. Maybe, that is why there is no sticker under the
hood that shows ignition timing?
Again, I have the factory book for my 95, but only, the Haynes for the 98.
It says to look for the sticker under the hood. There is a sticker that
covers plugs, valve clearances, but not ignition timing. My plan was to
just check the timing. I have reviewed over 500 posts on Civic Ignition
Timing. Topic 8457 was quite interesting under Honda General, but there
was confusion about the one (and only one)connector lighting the CEL.
Also which of the three marks (not counting the fourth mark which is
TDC)do you set the timing to? Thanks in advance for your assistance!

 

The procedure for the 98 Civic available via the link below
seems pretty good.

Go to the "Maintenance and Tuneup" section, then "Ignition
timing."

After the paper clip is installed in the service check
connector, you want to see that the center mark of the three
marks close together aligns with the pointer on the TB
cover.
