Use an S13 DOHC harness. Plugs right in under the hood, mild repinning inside. You're in for five times the work to adapt an S14 harness into a SOHC.

Same motor smart guy.

Do a search, the info you need is been violently discussed numerous times. I'm not patient enough to type it all out for you.
