Switching voltage polarity

Switching voltage polarity test for one half of an old B-17 ILS. Project is to hook up an Arduino to the instrument to move an indicator. The ILS Instrument has an input with four pins ( two for a horizontal and two for a vertical indicator). The dial is centered and functions depending on positive voltage going to one of the two pins. Noob here so comment if you know a better way to do this.

monolithic stereo audio amplifier ICs would make a really simple driver for this, should be one or more in any old television
