Hello all, i just got a HKS F-Con V off of a friend for a very good price that i couldn't pass up so i just got it. now im wondering where there is a user manual. ive checked online and ive looked here and theres frankly not much there about it. also just wondering theres like 4 bullet connectors that are covered in plastic , any one have any ideas what they go to???

any help is appreciated

heres a pic of what the connectors look like
i know the plastic ones go to the GCC for it

 

It is not accessible by the end user and does in fact require a PRO dealer who can tune.
