The stalk adaptor is to be used with a stalk interface.
The adaptor provides the correct connection to the aftermarket radio.

Technial Note
On certain applications when the stalk interface does not operate it maybe necessary to solder a 1K resistor inline between the remote control from the aftermarket radio and the stalk interface wires.
