Thanks for the reply, I looked further into my wiring problem and found one comment about using the thicker wires in the bundle of wires.
I also saw that someone said to connect the green wire on the new actuator to the blue/green wire on the old actuator,so i did this and it works
good. I think that the blue/green wire is the neutral wire for all the doors and the other wire the power wire and a different color for each door.
