y cables attenuation help

[RugnarStormBorn]

Can we run one y cable from the digital side car to two Talons that control two bag motors. Both of these motor will receive the same control command.

I know that we need a talon for each motor but do we need a pwm for each motor and talon?

What is also unclear, is whether there will be enough signal strength from the side car to both talons? Does y-ing the digital side car pwm reduce signal voltage?

Finally we may be running 4 cim motors on our transmission. Once again can we y the pwm cables to these motors?

Thanks in advance!
