Yes, your red wire is for ignition, yellow wire is for battery and black is ground. The red ignition wire is for the radio to turn off and on with the ignition. The yellow is always hot, for memory.

I need to know the wiring dia


all your wiring is color coated. if you have your harness from the the new reciever and you have purchased an adaptor harness which plugs into the vehicles existing harness enableling you to wire every thing as it is color coated you have red wire a yellow wire a black wire. your red and yellow are power and your black is your ground wire .your red should be be your acc or ignition wire which gives you power to the unit when the ignition is on should tie directly to the red wire on your adaptor harness, the yellow is your constant 12 volts which is for memory and keep your presest along with your time and features such as that it will tie with the yellow on the harness as well then the black is your ground the unit and will tie with the black wire on the harness. that takes care with powering the unit next you have a set of wires that you will be using to tie your sound to they are color coated as well and will tie to the new harness your front left and front right channels are white/white and black and usually gray/w a gray and white for the right channel thats your front. your rear is green/w green and purple and purple/w purple and white stripe for the rear speakers i hope that helps you out a bit
