On my 98 RS there were some 2 wire clips on the factory wiring harness that just plugged in place. When unplugged the hang a couple inches below the surface on the dash. You should be able to see what the harness looks like if you remove the tweeter and then look under the dash on the driver's side. It is almost a clear shot straight up. The passenger side is a little bit harder to access without taking the glove box out.

For what it's worth, I hope my info helps.
