I had asked this question before, hopefully some can help me. my original radio was the basic am/fm single cd, no sat radio. My original steering wheel did not have the radio controls in it. I replaced it with one that has the controls and I plugged it into the clock spring. I noticed that there is only 2 plugs when i replaced the radio with an aftermarket unit, not 3 plugs. Is there maybe a plug hidden I should be looking for or do I need to replace the harness for the third plug for the radio controls for the back of the radio? Any help is greatly appreciated.
