I do not have the manual for my headunit, nor can i get one for free, so if i cant do it myself ill just pay an extra £10 and get someone to install it for me.. (£20 for manual to be ordered).

Anyway ive been trying to figure out the wiring layout of my ISO Connector/block that came with my headunit, and ive managed to find this, by someone who also has the same headunit as me, (found it on some dead forums archives in the depths of the internet):

Orange = +12V constant

Red = +12V switched

Black = ground

Green/Black = Left Front -

Green = Left Front +

Grey/Black = Right Front -

Grey = Right Front +

Black/White = Right Rear -

Grey/Red = Right Rear +

Black/Green = Left Rear -

Green/Red = Left Rear +
(the wiring diagram for the ISO connector/block that comes with my headunit (DEH-890)

however, i still have two wires, which were not listed on this post i found:

A blue Wire & A Yellow wire, which funnily enough happen to be the only two wires with their factory descriptions attached to them, they state:

Blue wire says:

"If this unit is combined with a power amplifier, connect its blue lead to the blue lead (system control terminal) of the power amplifier. If combined with an auto-antenna, connect its blue lead to the relay control terminal of the auto-antenna (MAX. 300mA, 12 V DC)"

The yellow wire says:

"To lighting switch terminal"

if anyone can tell me if i need these or not?

also, the orange wire (the +12 V Constant) has two black plastic blocks along the wire, which i presume are some sort of fuse's as one of them says "10A", as u can see in the previous images i took of the cars original wiring my car already has a +12V Constant running from the battery or what ever, which is brown and red.

How would i attach these? would i have to cut the original brown/red +12V constant above its fuse and then attach my wire to it? with the new headunits fuse?

Once i know im not missing anything and im not gonna blow anything i can then wire this up with confidence!

Also on the back of my headunit i have a black wire leading to what i am certain is a co-axial connecter (i presume this is for the antenna?).. do i just wire a co-axial input plug on the end of my current antenna wire?

ALMOST THERE! WAHOO! THNX GUYS!
