AEM S2 EMS part number confusion.

[Nesquick]

k so im confused about the part number for the S2 AEM EMS.

from their site it says "30-6620". so i search around that part number, call a few places, and iv come up with it fitting only for a maxima. another place said for 300zx only. and now im confused.

can anyone please clarify why they have the same part number for different vehicles?

heres the link to the site: http://www.aemelectronics.com/engine-ma ... system-30/
scroll down till the part number is "30-6620" (3/4ish down first page)

im looking for a R33 RB26 M/T no UEGO if someone knows the exact number i need

thanks for the clarification
