replaced factory radio with after market radio i need the wiring diagram to properly hook up
-----Answer-----
Hi There,
What radio? is it a DIN fitting?
The radio will come with a wiring diagram so you need to know the car's wiring but only one way to do a "proper job" and that is to get an adaptor harness.
you need one of these kits anyway.

have fun, Peter
some one cut the end off so there fore i dont know what wires go where the other radio wasnt hooked up correctly so i need a diagram that shows speaker positives and negatives also the car has a external factory amp
AnswerHi Ray,
Didn't know the harness had been vandalised, (Oh why do they do it?)
Below is an instant experts course in radio installation, follow it and you will be up and running in no time.
The amp will be fed either by high level from the speaker wires or low level from 4 RCA leads, (front and rear, left and right) and switched on by the (blue?) wire from the radio's live OUT signal wire.
Enjoy, Peter.
You will need a test meter set to 20vdc or a 12v lamp or test probe.
I run this test when working on a car where a previous owner has ripped the connectors out of a used car and the new owner is in the same boat as you so it cover all the basics and should sort you out. So armed with your 12v probe or test meter, some paper, masking tape and a felt tip pen, here ya go!
Speaker wires. (non-amplified) these are tested with a AA battery across a pair of wires and you will here a 'pop' from the speaker,
These are normally twisted together in pairs (if you are lucky) and usually in a loom of their own before going of to the four corners of the car and are the same colour for each pair but one with a colour trace on, i.e. blue and blue/white, green and green/white.
Label it (e.g. left rear), continue until all four pairs are identified and labelled.
Earth one side of your meter or tester to a metal part of the car, probe each wire until you have a wire that is live all the time with the ignition OFF, label this ‘+30’.
Switch on ignition and redo test until you find another previously dead wire now live, this is ‘+15’.
Switch off ignition and switch on the side / park lights, repeat test until you find a third live, label this ‘lights’. Switch off the lights
You should now have two or three left. One will be earth, (usually black or brown); one could be to an amp and or electric ariel (usually blue or blue white) and one for phone mute if fitted. Clip tester to +30 and probe one of the remaining wires, if you have an electric ariel it will go up. Connect your DIN plug to the correct wires and jobs a good un’.
DIN connections are.
