Stereo help

Ok, so I've decided to install a stereo myself. Got the wire harnesses sorted for my car and the stereo. Seems pretty straight forward. But, this stereo is a Jap import, and wiring seems to be all mixed up to the one in the instructions...

I've tried looking up on net but got fuck all in the ways of manual for the particular stereo that I have...

The stereo I have is Pioneer Carrozzeria FH-P900MD.

Any advice would be much appriciated.

Can you ask the people you bought it off for a copy of the wiring diagram?

Is there a wiring harness plugged into the stereo already, if so do you have a picture of the back of the stereo? Its fairly standard the wiring between all stereo's these days so can probably tell you what is what, the only thing is knowing what is what within the car since different makes and models have different wiring

i could probably figure it out if i actually saw the headdeck.... could you post a photo of the wiring??

Lets assume that pioneer has standard wiring conventions across it's products, (and that they resemble standard wiring conventions everywhere).
This would make Orange constant (+) power.
Red (+) = ignition power
Black = ground

Right that's the easy bit.
Green or yellow might usually be the light switch (when you put the lights on, the face lights up). You might want to leave this until last to see what you have at the end.

Now I've pulled my diagram from my old car stereo out.
Blue= system remote (turns on an amp or power antenna, max 300ma 12v +)

White was for some door alarm feature and yellow/black was for cellular mute.

You should have 8 striped wires left for speakers front & rear. You can probably pare them off by colouring. Whoops, hang on, this wiring diagram has one pure green wire (left) and one pure grey wire (right). But all the others are based on this with green-another colour and grey/other colour. Using a speaker you can test the stereo once hooked up to power to figure out which wires are which, use the balance and fader to isolate each speaker. Mark the wires. Once all this is accounted for, you can come back to the lighting wire (which is perhaps yellow). Provided that it's the only wire left, you can test it with power, perhaps a fuse in between.

Post up the wires if unsure.

I agree with Ratbag's description, of course you only need the speaker wires though if you're going to wire directly to the headunit but it all sounds spot on

agreed...

Agreed.

Mean. Thanks guys. Got it all sorted. It was a bit a mission trying to fit that big ass stereo and all the wiring into the dash, but after hours of swearing and kicking the fence few times I got it in and going.
