280ZX Power Antenna with Aftermarket Radio

So after reading the schematic, trying to make heads or tails, I finally figured out how to make the power antenna work like factory with an after market stereo installation.

Hopefully the back of your (new) radio has an "antenna control" wire included.

This antenna control wire should be butt spliced into the (factory) green wire that goes into the factory radio. On my 82 NA car it was on a 4pin plug that had only 3 pins used.

Next, the (factory) antenna control 4pin plug with only 3 pins, "Blue"," Blue and Red", "Blue and White" that is connected the antenna button for short range or long range (skinny switch with an antenna symbol). The "Blue" and "Blue and Red" need to be spliced together and secured with your favorite method. I pulled the pins from the plug and soldered them together then wrapped tightly with electrical tape around the factory wire bundle.

This will allow the radio on/off button to raise and lower the power antenna, or when you turn your car on/off with the radio on, the antenna will raise and lower as well.

Enjoy.
