3. You cut the PWM connector off a servo and connected the black and red wires to Motor 1 or 2 on the Sabertooth.
Then you powered everything on, and I'm guessing the wires from the servo to the sabertooth melted and the servo went up in smoke, yes?

Somewhat correct. The Tetrix motor was plugged into motor 2. I used a male to female PWM, cut the end off on the male side, and stripped and inserted that side to the motor 1 terminal on the saber tooth, then I used a long PWM male to female connecting to the servos PWM( the arm is hollow so I ran the wire down the inside ). I didn't modify the servo or the wires in any way except stripping one end to plug it into the sabertooth. In between the long PWM wire and the wire connected to the sabertooth I placed two single pin jumper wires, because both ends were female connectors. As soon as I powered on, the arm jerked a little ( that was the Tetrix motor) then using the rc remote I commanded the Tetrix to move. It did not, and then I commaned the servo, and the two jumpers immediately went up in smoke so I ripped them out by hand ( got burnt but it's better than the alternative of setting the building fire suppression off ). No smoke whatsoever came from the servo, and the receiver and sabertooth have their own separate power supplies.
Edit: i cannot get back to the shop until Monday so I cannot inspect the servo and the wiring until then. I'm assuming I did it wrong,I dont think it was the servos fault. When I get back I'll post a photo of the setup I was using ( with replaced wires to show where I put the jumpers ).
