my turn to ask for help
so, i'm in there digging around in the wiring while installing the new stereo, and once again i came upon the skinny brown wire with a blue stripe - this car has always had an aftermarket stereo in it since i got it, and subsequent systems worked fine, with no ill effect from that wire not going anywhere, so i never bothered to figure out what it was for
well, this time i just really wanted to know, because i am going to button it up once and for all this time
it has about .4 volts on it - that tells me it's a sensor wire - a look at the wiring diagram confirmed it - it was the radio alarm contact wire - this goes to ground after going through the radio case
my theory is this: the system is constantly "seeking" a connection to the radio, and sees this sort of like an open contact switch, but for whatever reason, doesn't trip the alarm
so, here's the $64,000 question: should this be grounded to the chassis? can this be grounded to the chassis? is there something else that needs to go inline first?
also, the skinny black wire that parallels the coaxial antenna cable, terminating at the antenna amplifier goes to the little molex and into the skinny red/black wire - that then went into the molex connector and plugged into the back of the factory radio - the question is this: is this ground or power that it should be connected to? the wiring diagram is no help, and i don't have factory radio to tap to see what is at that pin - also, why the heck is that wire black?
