wow...you got screwed. ONLY 95-98 Civics needed that T-harness for retaining the factory radio. This was ONLY needed if you are sporting factory keyless entry and wanted to keep it working. Otherwise, there is nothing to worry about except for the dome light not working.
The dome light thing can be fixed by placing a jumper between two wires on the green-colored socket that goes into the OEM radio. The two wires are Light Green/Red and Light Green/Black. Connect these two and the dome light works normally again....no t-harness.
Again, this ONLY applies to 95-98 Civics.

PS: I work at Circuit City roadshop, and we only charge an extra $5 for the t-harness, and we've done so many of these that we don't charge any extra labor either.
