yeah, 2nd gens have different leading/trailing plugs, but on the 1st gen they're all the same.
Choose either BR8EQ-14s or BR9EQ-14s, the 8s are city, 9s are highway

Small correction.
SA's with stock dist do not use the above plugs. Only if they have been converted over to FB systems.
Forgot to add that the 12a's use the 8's whether city or highway. The 13b's use the 8's or 9's depending.
