yellow wire with black mark on end - from fuse 8 - constant power feed (memory)

 

Blue wire - from fuse 2 - ignition switched supply

 

Orange wire - from fuse 12 - supply from lights on (to dim radio display at night)

 

Yellow wire with brown mark on end - Earth

 

 

All the green wires are speaker connections with a coloured trace on the end of them

 

green grey +ve + green yellow -ve = N/S/F

 

green red +ve + green brown -ve = O/S/F

 

green +ve + green white -ve = N/S/R

 

green black +ve + green blue -ve O/S/R

 

I hope that lot mkes sense to you.

thankyou! your a star! one more audio related problem.... my head unit which i have bought does not have an earth wire.... just has a black wire labeled (ground).... is that my earth because i would of thought that was my negitave?

[kfk]

Yes your ground wire will be earth or negative

sorted!!! but iv'e just tried to wire and it made the sound like it was working for about 3seconds.... then all of a sudden just stoped, now it wont do nout! and iv'e checked all my fuses...

 

i really don't wanna give in and fork out and extra £40 so the ppl at halfords can mess about with it!

So have you got a power feed:

 

yellow wire with black mark on end - from fuse 8 - constant power feed

 

Blue wire - from fuse 2 - with ignition on

 

Orange wire - from fuse 12 - with lights on

 

Does your cigarette lighter work?

 

If memory serves me correctly the cigar lighter runs of the same fuse as the radio, and turning up my JVC unit would draw more current than the standard fuse liked.....hence it would blow the fuse.

it's all good... ive attached my power to batery to the blue wire... but now my blowers dont work! the to batery (positive) is connected and the ground (negative) wire is connected to the yellow with brown...when there connected for the first 5 seconds the head unit sounds like its working but then just stops and i cant get nothing from the head unit. (batery icon shows up then disappears whilst head unit is making sound)... but that still leaves me with the yellow with green mark wire not connected...and still no tunes...

 

i had to cut the blue wire... and attach the to ignition wire to it using a block!

 

im so confused as to why its not working!

[Guest Gee]

wey hey!!! done it!!! word of advice for all the other people trying to fit a head unit without an earth wire... don't attach the "to ignition" to the blue wire but attach it to the "to batery" wire on the head unit and then to the "live feed" and then your negative to negative (ground), but dont forget to remove the front of your head unit when your not driving or listening to music!!!

 

sorted another problem solved thanks to the members on this forum!!! especially thanks to KFK!!!

 

Gee
