Replacing the rumble motor on a Gamesir G7 SE

I have an out-of-warranty Gamesir G7 SE. The left grip motor only works when the controller is either shaken or tapped/hit against a hard surface.  The motor works for a while and then dies out again. Contact cleaner didn't help.

Can I use a motor from another (XBox or PlayStation) controller to replace it?  I know I would have to reuse the old (Gamesir) connector and re-solder the wires.  Which colored wires should be soldered together?   I'm presuming Gamesir black to (XBox/PlayStation) black and Gamesir gray to (XBox/PlayStation) red.

The motor inside the right-handed trigger is out completely, but my priority is focused on the motor inside the left-handed grip.
