I purchased some connectors at Radio Shack that fit the fuse box terminals and would crimp onto the wires. Fortunately, GM used a "Y" type connector when they used the terminals for options like the clock so the terminals were available.
I wish I had used better looking wire but it is what I could find at the time.
Yellow picks up the dimmer-controlled power for the light.
White picks up "acc" accessory power to turn on the radio.
Brown picks up the constant 24/7 +12v for preserving the stations' programming.
