Hello, this is John, my rotary luck is non existent. and a long list of reasons have led up to the current problem. i couldn't find any posts with a very similar problem. kinda but not as much info as i would like. so i have a '93 rx7. i also have a '96 rx7 motor in it. now i have an aem ems for a '93-'95 rx7. So my problem is... what do i do? i have the harness out of the '93. so the 96 harness is on it right now, but in order to run the aem, can i use the jdm harness? i guess this would be a question for aem, but they told me to run the 93 harness. however just to satisfy my own curiosity, isn't the aem just a blank computer? if i load a base map i guess it would be effected? ok nevermind that, the important thing is how bad is it to switch to a usdm harness on a jdm motor, but more importantly a '93 harnes to a '96 jdm motor. well even if you yell at me and lead me to a thread that covers this that i overlooked, anything would be very greatly apperciated. thank you.
