finally bought a head unit to replace my crappy old, non-bose unit.
just have 1 question.

for the wiring theres a blue/white wire that says:
connect to system control terminal of the power amp or auto-antenna relay control terminal (max 300mA 12 V DC).
where can i find this? can anyone w/ a FSM point it out?

 

Why aren't you using a wiring harness? metra 70-7551 /thread.

 

what are you talking about? it came w/ a wiring harness.
whats the diff between the metra and the already provided harness?

 

Already provided is made for the radio Metra (or company of choice) is for your CAR.

 

its the remote wire that tell the amp your using to turn on or off. You could hook it up to the remote wire that the HU has or wrap it around a fuse that controls something that turns on everytime your car does. Like the radio fuse, you could wrap it around that and everytime the radio came on so would the amp. So If you get an amp later and dont feel like taking the HU out again, you can take this shortcut.
