stereo wiring question
I am about to install my head unit (hope I don't get that alternator noise I been reading about). I am going to bypass the factory amp. I went through the installs section and came across the wiring for a gts . I got a few questions.
Caps are main color followed by stripe.
GRAY w/silver dots 12V ACC
BLUE w/yellow stripe 12V Constant
WHITE w/green dimmer
WHITE sig left front <------what is this
YELLOW sig left rear <------ this
RED sig right front <------this
BLUE sig right rear <-------- this
GRAY/shrink sig shield (all) <----- and this ?????
what is sig. I am guessing its signal but i am not sure.
