I believe the typical connection if equipped with dash and the underseat heater was both heaters in parallel and only one switch controlled them. If the owner wanted to separate them, an optional switch was sometimes installed in the dash if there was an unused slot say in the fog or electromatic switch position. If nothing was available then one of the earlier screw on type switches was placed under the dash edge for the underseat heater.

If you already have separate controls I would treat it as such and take the power for the second heater from ignition switch via a separate fused feed.
