I am working on a project to make a car suspension using an Arduino uno r3 powered by a 9v battery to control 4 MG996R servo motors powered by a 6v 2000 mAh battery pack and was wondering how i would wire each to have sufficient power
Wire the power and GND leads of each of the servos to the 6V supply and each of their control leads to individual pins on the Uno
Connect the GND wire of the 6V supply to a GND pin on the Uno so that the servos and Uno have a common voltage level as a reference for signal levels
Where you may have problems is with the 9V battery supply of the Uno. If it is of the battery type designed to power smoke detectors for long periods at low current then it will not last long powering the Uno at the required current even though the servos are powered externally
How could i incorporate an hc-10 bluetooth module into this as well
Tie strap it to the back of the Arduino board? Unless there's something specific that you want it to do. If you want it to do something specific then you should connect it to the board and write some code for it. It all depends on what you want it to do.

Make a "shield" for a more reliable connection (than jumper wires) at a much lower cost than COTS...
