Ok I need some help finishing up my stereo install.

I took out the old radio, cut a much bigger square in the console to fit the new stereo, hooked up the antenna input (just plugged it in). I have stripped the speaker wires, and the antenna power wire, and hooked them up to the stereo. I am pretty confident that I got it correct so far.

There is some other wires for an amplifier, some kind of phone thing (I guess it has the capability for a car phone), and rear speakers. All of which I don't have. So I'm all set there.

Now there is three wires left coming out of the stereo. The manual says this.

Red - Ignition
Yellow - Battery
Black - Ground


I am going to put the ground on the grounding point behind the console. So that is all set.

Now what wires do I hook up the Ignition and Battery wires to? I am having a hard time reading the wiring diagrams in the manuals off of BMW320i.com and I don't know what the colors are.

There is these 2 purple striped wires and a blue striped wire which are connected with plugs and then merge into a red wire which is connected to a fuse holder thing, and a yellow plug on this end. (This was all plugged into the back of the factory radio.) So I assume this is what I need to work with, but I don't know if I am right. I assume the fuse thing should just be cut off and restrip the wire. (The new stereo already has a fuse on the back of it.

It looks like this....

Okay. Here is my question:

Where do I connect the ignition wire and battery wire from my stereo's wire harness to the wires in the car? (So I can get power.)

on my 320i 83'

the ignition is purple and the red w/ yellow stripe is the power. make sure you have a fuse on the power wire even if you have one on your deck.

So the one in the diagram I drew above is is the power? (It has the fuse.) What kind of fuse do I need?

I am not sure which one is the ignition, is it neccisary for me to connect the ignition wire? That just means I can use it when the car is ACC mode right?

Does the fuse have to be the same as my new stereo deck???

you need a 15amp fuse on power and yoiu also have to have the ignition wire inorder for yoiur stereo to turn on and off when the car is on or off. you need it!

Ok thanks. I wasn't sure which one to use, because I couldn't find any mention of it in the manual, but my manual is kind of messed up and missing pages. My stereo has a 10amp fuse on the back so, I didn;'t know if that would be enough. I have my Haynes manual on its way, and tomorrow I am going to pick up a wire tester to I can figure out which one is the battery, which one is the ignition.

heres a quick tip, the power one is USUALLY thicker then rest.
