I'm trying to install my new JVC head unit and im at a loss as to what colours from the original head unit go to what. I've been searching everywhere for diagrams but none have specificly said whether it applys to 93 TRs.
Any help would be grand.

get a testing tool or a like it'll show you which is + power and continuos. then just trial and error for the speakers buddy. if i still had my TR i'd be able to tell you which is which but I don't so thats all I can say.
