EDIT: Another suggestion is to cover all newly exposed metal with something to prevent rust (suggestion by: DeSchlong).

Upon my initial research to determine the side marker location of the 92-95 Civic EG 4dr (sedan), I discovered that the location of the side markers (in relation to the side trim/molding), are DIFFERENT between the 2/3dr and 4dr EGs.
Based on images of the 92-95 Civic EG 4dr (sedan) fenders with factory installed side markers (e.g., JDM, EDM), I revised the original [92-95 Civic EG 2/3dr Side Marker Template] for a "92-95 Civic EG 4dr (sedan)" application. I repeat, "I did not have actual JDM/EDM Civic EG 4dr fenders in my possession," and therefore, the location I have implied in my [92-95 Civic EG 4dr (sedan) Side Marker Template] is approximate but comparatively accurate.
The [92-95 Civic EG 4dr (sedan) Side Marker Template] is attached to the bottom of this post.
The following subsequent information is a basic guideline that I have outlined during the course of my own installation procedure. You (or your installer) may rely on this information at his/her own risk.
Caveat and limitations: Installer should be comfortable and experienced working with power tools. I will not take responsibility for undesired outcomes that results in loss or injury. Eye protection and general safety is the responsibility of the installer.
Here's a general step-by-step outline of what I did:
1. Use the template (attached to the bottom of this post) to mask the location of the hole for the sidemarker.
*Consider ONLY the rectangular portion of the cutout, as shown in the red outline below.
2. Here, I cut the template and used the [top edge of the trim indentation] and [trailing edge of the fender] as the reference point, as shown by the red arrow below.
3. I masked the area to be cut and double-checked the location with the measurements, as shown in the template. Adjust as necessary.
I then outlined 6/32" from borders of the masked area using a fine tip Sharpie.
*I measured 6/32" because I will drill 5/16" holes at each corner, leaving a 1/32" margin.
4. I started with 1/16" drill bit at the intersection of the marked outline. Then increased to a larger 13/64" bit, then 1/4", and finally 5/16."
*BE CAREFUL not to drill outside of the masked area.
5. Next I used a dremel with a cutoff wheel to grind between each 5/16" hole, carefully following the edge of the masked area.
From there, you grind a little more...[think baby steps]...making the edges straight of the rectangular hole.
For the corners, I used a cylindrical grinding stone to smooth the corners out and to align it to the straight edges of the rectangular hole. You may choose to make 90 degree corners at your discretion, as shown in the template.
*Be careful NOT to grind outside the masked area.
6. I relocated the masking tape on the trailing edge of the fender about 2mm. This is where I made a small indented cut like the template shows.
(In my case, the 2nd indented cut, as shown in the template was not needed.)
Be sure to test fit the sidemarker; make this an easier task by temporarily removing the retaining clip on the sidemarker.
If the rectangular hole is too small, you need to choose one side that needs to be opened more and then grinding slightly outside of the masked area. You may consider relocating the masking tape in 1mm increments to help.
(In my case, I needed to relocate the top edge an additional 1mm.)
*Remember to grind LITTLE-BY-LITTLE and test fit after each moment that you grind.
7. Once your sidemarker fits, reinstall the retaining clip and do another test fit. This is the point where you can adjust the spring tension of the retaining clip (by slightly bending it), which secures the sidemarker.
7. At this point you should be done with the physical installation! You may also consider masking the exposed edges of the hole to spray down a rust-preventing spray. Goodluck!
