Wire colors in your car might be different
than colors described here. Use the given colors for reference purposes only.
Always test wires to make sure they are correct. We are not responsible for any
misprints.
To check hot, ignition, lights, dimmer, use a test
light or voltmeter. To check speakers use test radio.
To check speaker polarity (assuming you don't have a
polarity tester): Touch (for a very short period of time) one wire to the positive side of
a 1.5-volt battery (any size), and the other wire to the negative side. If speaker
"pops out", then polarity is correct. If speaker "pops in" then
polarity is reversed. Make sure that the wires you are going to check for speakers
do not have any power.
