Do I just wire it to the same terminals as the blower motor on the circuit board or is there another set of terminals for that purpose. Not my furnace so I don't know what make and model....it's for a friend.
Thanks much for any input or links.

I know on some heating systems, the furnace blower is wired from the low voltage on the circuit board to a 120 volt relay to power the blower---if the duct booster fan is rated for the same low voltage as the circuit board, can I just wire it to the same terminals as the blower? I'm thinking the duct booster is not 120 volts but more like 24---only 5-6 inch diameter fan on the booster and the wiring is small diameter.

You need to be sure the voltages for the the blower and duct fan motors are the same. It is pretty sure both will be single phase, but they must be the same. The blower motor may have more than one speed. Normally there is a higher speed for air conditioning and a lower speed for heating. Without the wiring schematic, it is nearly impossible for anyone to give you a correct answer.

One solution is through a relay that powers the blower from a seperate source. The relay would be powered from the main blower when it comes on. A hvac tech should be able to do it or call an electrician.
