S13/S13 harness is very easy to convert to S13/S14 swap harness, as long as you have an S14 F3 plug, and S14 wiper plugs available. It would be a waste of time to go searching for another stock s13 sr harness when he already has one. Just make sure you have a complete uncut s14 ka harness, and you will not need anything else.
