The red is the power for the radio. Yellow is the constant power which keeps your tuned stations saved in the memory and keeps your head unit's clock running and on the correct time. This is universal color code for car radio's.
To check correct hookup, switch ignition off. Test the yellow wire on the car for power using a multimeter or connect a 12V bulb between the yellow wire and a proper ground point. If you get no power you either have the wrong wire, a blown fuse or the wire is disconnected/broken. Do the same with the red wire. Here you should find no power with the ignition off.
Switch on the ignition. You should now have power on both red and yellow.
Connect the wire that where you found power with the ignition both off and on(should be yellow) to the yellow on the head unit. The other would then go on the red of the head unit. With this type of hook-up the radio would switch off with the ignition turned off, but will still retain its station and setting memory and clock time.
It is permissable to connect the red and yellow from the radio together and connect them to the permanently powered wire.
This will enable you to use the unit even without the ignition switched on. The downside is forgetting to turn the unit off and getting back to a car with a flat battery the next morning.
Remember to connect a decent earth wire to the black coming from the radio. The grounding provided by the antenna alone is not recommended.

99 dodge 1500 p/u has intermittrnt heating/cooling in the a/c mode.cools for about 1 minute then blows hot air for about 5 secs then cool again.any thoughts?


You may have over filled the freon. If the a/c system has to much pressure the pump kicks off and on. Hook a pressure gauge to it. Typically these rams take 2 cans of freon. Or 1.8 lbs i think. Your gauge should be in the blue/green area.. Not the yellow or the red. Hope this helps

In the mix of wires there will be a constant wire. this is usually labeled on the back of your deck this is the wire that need to be hooked into the hot wire. this will provide constant power to the radio that will help it keep the time,position on cd when powered off and other info.

1998 Dodge Ram radio


Well, some how, the wiring for the front speakers didn't get hooked up or hooked up improperly. I assume it is a new cd player? If not, maybe it's the player itself.
