can someone please tell me how to figure if an aem ems is an older or newer box? i have a 97 gsr, but i have an obd2-1 jumper. so im guessing i can use the 30-1000 which is for obd1 harnesses, but is there a newer box with a diff. serial #?? or have the serial #'s stayed the same? how can i tell? i dunno. any help is appreciated.

 

aempower.com should have all of the part numbers on it for ya
