its connected to something on the oter side of the firewall. my s13 has 1 im trying to get rid of as well. gotta take off the dash, and its above the cabin filter and motor. i think it might be for heat/air or something. either way, i disconnected all the electrical on mine, and it started just fine. you don't need it. and the wiper motor is located right next to that as well, wiper motor has the lines that look like vaccuum lines, but they're running to the sprayers. get rid of it.
