sony head unit,

[strap-on]

i have three wires that i cant work out a blue one a light blue one and a blue with a white stripe anyone know what they are?

[samlloyd]

Blue = ellec aeiral
w/stripe = remote for amp

light blue could be for illumination. Just google sony wiring diagram

*will not be held responsible for advice given

Pretty sure light blue is an ATT wire. Check the other two to be sure, aerial one will only be on with the radio and the other should be live all the time the unit is on (for amps)

[samlloyd]

Have a go earthing the possible antena(sp) wire, some of them will make a noise when its earth( mine did)

got it

Blue was arial
light blue was att
blue with stripe was system remote control

had a bit of a hard time getting the arial to work, i thought the cable that it was was the earth cable, i got it going only to find its broken, the motor spins but the arial wont go up or down,so i gotta pull it out
