Need Help Identifying my ECU

[newdude1]

Im trying to figure out exactly what s14sr motor I have whether its an older or newer one. I know you can look at the sticker on the ecu but mine is ripped off. Only a corner is left and its black if that helps any. Is there any other way to id them? Im tryin to buy a used Jim Wolf ecu.

You can look at the pin layouts, the later S14 has the same pin layout as the S13 SR's. The S14 early blacktop pinout is different from the other two. Go to the ApexI website, download the wiring diagram for an SAFC and look at the ECU pinouts, it will be easy to differentiate the two ecus.
