How do I connect a JVC receiver to the ignition switch?
I am replacing the OEM radio with a JVC cd player. JVC support says that it needs to be connected to the ignition switch to operate properly. The wiring harness does not connect it. Where is the connection for the ignition switch? One other site said to run a wire to the fuse box.

You need to get a testing meter, connect the black lead from the testing meter to the car ground. and one to the pin in the connectors. Do this with the car ignition switch on, find one that's live, then turn the ignition switch off it should go off. then just cut the wire and connect it together. make sure you have a good ground lead connected to the ground of the car.

The yellow wire in the wiring harness of your head unit must be connected to a constant power source, a live terminal in the fuse block that is connected to the battery and not affected by the ignition switch. If you do not have your manual this may help: http://resources.jvc.com/Resources/00/00/95/GET0182-002A.pdf
Do not cut the wires from the car. Instead, call Crutchfield at 888-955-6000 and order the adapter part number 120701003. When you call them, ask for color coding. For JVC, refer to the attached picture. Match the adapter color code with that of JVC. If the adapter color code is the same, then connect ground (black), battery (yellow), and wire from ignition switch (red) securely. Turn on the car and see the radio works. If it works, connect one by one speakers and confirm. Remember, perfect connection gives reliable installation.
im bit confused, if you are going to use this radio in car, or outside, using car battery.....? anyway, this how you hookup all the wires..
+YELOW WIRE,- DIRECT FROM BATTERY TERMNIAL..12+
+RED- MAIN WIRE..CONNECTED TO ACC/IGNITION SWITCH, ALSO 12V+
-BLACK- NEGTIVE, GROUNDING WIRE 12V-
WHITE TO WHITE/BLK----SPEAKER
GREY TO GREY-----SPEAKER
PURPLE TO PURPLE------SPEAKER
if you are using outside the car using car battery, then you can twist yellow and red togather..for postive 12v+
As a sanity check run a temporary wire directly from the battery positive to the radio. Twist the red and yellow wires together and connect it to the wire from the battery. If this works either your red or yellow wire connection under the dash or to the harness is not hot like you think. Yellow usually goes to a constant 12 volt source (to keep radio memory) and the red wire to 12volts when the ignition is on. In some radios this is reversed. The test I mentioned will determin if the problem is in the wiring or the radio.
