** talking S14 Zenki sr20det ECUs- just so we're on the same page**

Hey guys,
Can some of you help me here. I've searched and came across two postings that try to explain the difference between the Zenki ECUs

WC-red lettering
WC-black lettering

According to this post (http://zilvia.net/f/tech-talk/121885-sr20det-wc-ecu-black-red-zenki-kouki.html#post1646767) RED WC is from a 95-96 S14 Silvia Zenki
BLACK WC is from a 96-97 S14 Silvia Chuki (transition, different MAF plug)

Is the difference in the MAF plug purely cosmetic? The WC-red rectangle plug and WC-blk oval plug?

Can I use the ECUs interchangably or is there a difference with the pinout and harnesses between these?

Red and black WC/WE Ecus for S14 sr20's are interchangable, just watch the maf plug difference.
