Yep. You have to trim off the the little Futaba alignment tab on the connector, might have to bevel the edges of the connector a bit, and make sure you plug them in with the right polarity.

The brown wire in the JR harness is the ground, same as the black in the Futaba wiring.

I have quite a few Futaba servos in use with JR receivers.

In general, you can use most Futaba servos with JR/Spektrum. The Futaba servos have a Polarity Fin that must be shaved off so the Futaba connector will fit in the JR/Spektrum female connector. Sometimes, you also have bevel the edges of the Futaba connector. The Futaba female connector will accept the JR/Spektrum male connector. Sometimes, I use MPI universal 3" extensions, to avoid trimming the Futaba connector. I have used combinations of JR and Futaba servos in the same aircraft.

JR/Spektrum male connectors have beveled edges on one side to ensure correct polarity. They are more like Hitec male connectors.
