sony m800 head unit help

[Deleted member 20482]

ok i have done a search on here and can't find anything...but i have a sony m800 head unit..old i know but still kicks ass...
i know by reading on here i need an aerial booster as radio reception crap...
i'm not sure which wire on my stereo to connect to the aerial booster..
dont have instructions anymore and sony haven't got it on their site either
i have on my wiring loom (except the speaker connections)
1 x yellow
1 x red
1 x black
1 x dark blue
1 x light blue wire with "att" on it
and 1 x blue with white stripe with "amp rem max 0.3A (i think its this 1 but need confirmation)
http://
any help is greatly appreciated as i have had to put back in my old tape aura and that doesn't connect to my sony cd changer in the boot cause i lost the "connects2" connector.
thanks people

Asume thats right! think thats a postive feed which turns on only when head unit is powered up!

so i guess i was right with blue and white stripe wire to aerial booster...thank you

i have heard it was a "blue" wire but i have 3 of them and didn't want to **** wiring up and melt something.

Try this! using a tester! on the head unit if it shows power and when you power of the head unit it should be off! Just to be on the safe side!

i think i have a multi meter somewhere..god knows where though.

do you know what sort of volts should be coming out of it and any idea what the aerial booster needs.

'amp rem' will be the amplifier remote turn on - used as a signal for amps elsewhere.

I'm not sure if that will power an aerial amplifier - I'm pretty sure it's a different cable in the Leon.

oh poo thats blown it then.. back to square 1.
anyone know what wire i should be looking for..
does the booster need a permanant live or switched live so it only comes on when the head unit turns on?
got one off flea bay but it doesn't look like there is no instructions...typical

why is it that sometimes web sites are not there 1 day and then they are..
anyway after some searching..found a wiring diagram..
i'm not very good at these things but am i correct in thinking its the solid blue wire..
abit slow on these things

Yup - solid blue 'ant rem' - usually used to move an electric aerial I think.
At least I think so - it's the one I would wire up.

thanks guys all sorted now.. solid dark blue wire..
wired it up and wow how many stations have i got now..and how clear...although abit of a squeeze getting everything in behind unit.

these leons have tight corner when fitting after market head units, espically when you have dozen phone leads. just a night mare getting it in!

glad its all sorted
