Working on Power Antenna modernization.

 

Watch Youtube video how 3rd party power antenna works. Since my power Antenna did not comes with any instruction(maybe I lost?)

 

Original power antenna is controlled up/down switch.

I want to control power antenna via modern car stereo with just one wire using existing cable.

 

Here is my schematic.

While Green wire connect to red with 12V, power antenna is extended. Once green cable is disconnected with red with 12V, the power antenna is go back to housing.

 

Power Antenna is installed.

 

Test with battery.

 

Works!

 

Need to connect Blue/Red to 12V constant.

Thank you, I'd like to do that too.  My old switch is just hanging under the newer stereo.
