IIRC brown is ground, RED / white is constant, and BROWN / red is accessory.  You do need to test these wires with a meter to verify them first, though.

My ex once told me I have a perfect face for radio.

ok, i think i'll wait and see about the alternator for now-wait till i'm up and running!

looks like the wiring on the link from arrow and what geepherder said confirm what geep said, but i really am a novice!

i.e. ground? constant?, accessory!?!?!?!?

and just incase-how do i test these-will it matter if they are not right and i put them to the earth, remote, and power on my head unit loom?

also-what wires are the power, remote, earth, and rear speakers on my head unit loom-wires as follows...

loom 1;-

8 wires

green & silver

green, silver & black

white & silver

white, silver & black

grey & silver

grey, silver & black

purple & silver

purple, silver & black

loom 2;-

6 wires

orange, white & silver

brown & silver

black & silver

blue, white & silver

yellow & silver-which has been linked half way via crimps

red & silver-which has been linked half way by crimps with a piece of red & silver wire spliced out of the crimps.

i'm assuming that loom 1 is the speakers-but which ones are rear speaker colours?

and i aint got a clue on loom 2 which wires to cut and attach to the 3 wires mentioned earlier for power, earth, and remote?

thanks as always

dont know if this helps-but i think the wire hanging from the red and silver one on the head unit loom was connected to the remote lead to the amps!?!?!?!i may be wrong,

and correct me if i'm wrong-but ground is the earth/negative, constant is the 12 volt power, and accessory is the remote from the igntion wiring from the key position,

so what i think i should do is put the ground(brown) to the black and silver on head loom

the constant (red & white), to the red and silver on head loom

the accessory (brown & red), to the blue, white & silver on head loom

and the remote lead from amps to the spare piece of red & silver on head loom?????????

again-correct me if i'm wrong-and is there a test i shoud do first to confirm on 3 car wires?

just been doing more research!!

correct me if i'm wrong as follows..

rear speakers are the green cables (left), and violet cables (right)

ground is the black and silver (so to the brown)

accessory is the RED and silver (so to the brown and red)

constant is the YELLOW and silver (so to the red and white)

and amp remote is the BLUE and WHITE (so to the remote lead from amps)

obviously this is pending the 3 car wires being what we think they are (can i test these without a meter-as i dont have one)

but it also leaves an orange & white cable, and brown cable on the loom doing nothing-is this important??,

and what about the spare piece of wire on the red and silver cable??
