Radio Wires - Updated first post

[Yoshi]

Just disconnected my original radio (NA6). and am not too sure what all the different wires are. (im installing a new radio)

There is the black grounding wire in the centre - I know what this one is.

A large black coaxial cable form the right - Is this power from the battery? If so my new radio say it needs both positive and negative, does this mean i will have to run another wire from the battery?

Two connectors with wires, one on top of the other, on the left hand side - Are there all the wires from the speakers? I have the two door speakers and the headrest speakers.

Can anyone help me out?


UPDATE: Yay got the radio going . The problem is i pulled out the speakers and forgot to mark which wire went on what connector. Does it matter? I have two wires, both red, one with a white stripe and the other with a green. Back at the radio connector end the wires are a different colour so i cant tell which is negative and positive. I connected it up to the speaker trying both combinations and they both worked. Does it matter which way i connect it to the speaker? I thought it, but it worked both ways.

Those gender changing looms that you can purchase would be the ideal way of installing an aftermarket head unit

....as for the wiring info, you may find it here

Antenna lead?

Wow thanks for all the links.

I just found a coaxial connection at the back of the radio, so i assume that this is NOT for the power. What is the coaxial cable for then, antenna?

In that case i also assume that power is coming from one of the two connectors. How can i find out which ones are for the power.

The reason why i ask is because the radio i bought comes with an adaptor on one end (that fits into the radio) and the other end is just wires, so i will have to do soldering even if i get the adaptor.

I know what all the wires mean on the back of the new radio, its just that i dont know what the ones in the car are.

Anyways its off to the shops to get me the adaptor.





Edit: I just saw a picture of the adaptor i need to get, looks easy because they are colour coded, matches the ones on the back of the new radio so i guess its just a case of matching colours So it shouldnt be a probem..
