PWM 2 motor isolation help

I'm new to this so please be kind. I need help trying to find the best way to do this since I like to over complicate things. I have a Throttle body motor that I am controlling with PWM. I need to piggyback off the 12VDC signal to control another throttle body motor. My main PWM signal will only power one safe. So I need to make something to use that PWM Signal to run the other Motor from another isolated driver. Any ideas?
Thanks
Kris

    I would recomend an op-amp circuit. The op-amp will have infinite resistance going in from the stamp then you can split the signal after the op-amp to send it to both motors. Look up a unity gain op-amp circuit online and you should be all set.
