S13 sr20det into a s14 what standalone?

[BROKENS14]

I have a 95 240sx with an s13 sr20det engine. I'm looking into getting a AEM ems but I need to know if I need to get the s13 ems or the s14 ems

your engine harness is?
Your ? would make perfectly good sense, if you had a hacked s14 sr harness running an s13 sr engine, but how would the people on the internets know?

You could have just asked whomever is going to tune it.
