A/C Wiring question

[rim_bender]

I just installed my S13 SR20. Using heavythrottles wiring diagram there is suppose to be 2 wires from the KA side and 2 wirs from the new SR20 harness for A/C relay. On my car i have 2 from the KA side and only one form the SR20 harness. I connected as much as i could but i still have that one A/C relay wired on the 240 side not connected to anythign. I dont have any wires left over to attach the last A/C relay wire to, so what does this mean. Is there another way to hook up the A/C. This is the wiring by the battery tray jsut to clarify. ALso this is on an S13 240sx.

Any help please
