OK, I will try and make this as simple as I can.
In this pic below, we have an E body AM radio. The
orange wire coming from the side of the case is the light. The red wire is the power going to the radio. They meet and are both in the same grey plug . Under your dash, somewhere near the radio, you should see the other end of this plug, which will feed the power AND light . Just plug it in .
As long as nobody has hacked up your under dash harness, you should see the other end of the radio plug very close to the radio .
