I do think you either need to re-pin a few of the wires or get a conversion harness to go between the two....I havent seen those for sale recently. Repinning is easy if you have both OEM pinout diagrams.
I've heard from a few people that the Mine's factory upboost tune for the CA is really just a slightly tweaked SR20DET OEM basemap, so I feel fairly confident the S14 unit will work once repinned (minus the butterfly solenoid). You can even get the D Jetro version and ditch your MAF!! Also, I believe the AEM EMS CA18 and S14 SR part number (30-1622) are the same...so...that confirms the use the same ECU plug. Anyhow...
