hey forum! so when i bought my RX-7 it came with a few boxes of goodies with it! im having trouble identifying a few of them and thought you guys might be able too for me! i know the one is the ECU, just there's a strange plug in on the one side, i don't know what thats for, if someone could identify what it is that'd be awesome!

 

#1 is a S5 Air flow meter,(AFM) depending on Part number,it could be either NA or TII.
#2 Most likely an S5 TII N374 JDM ECU.
#3 same.
#4 Power antenna for stereo...Mr Music please!
#5 Charcoal cannister for emissions.(fuel vapor)

 

So in the third picture, it shows that black connector that's attached to the ECU, well that's what stumps me, what is it, I can find what plugs into it anywhere, could you, or someone, please give me some info on it? It would help a lot

 

Japanese wiring is different than the USDM wiring.
A lot of guys just plain don't like using that Ecu.

 

So it's for the jdm wiring harness? Cause right now, I have my S5 JDM turbo just plugged into the USDM Ecu and not this one, would it be smartest to leave it with the USDM ecu? Or to put in the JDM?
