Hi Jeff,
What is the draw? You say little draw. A draw of 1 - 3 amps can drain battery enough over night that vehicle won't turn over. Also I suggest you remove the battery disconnect. It is not good for newer vehicles. It can create a relearn proccess which will cause you vehicle to run rough and/or have other drivability problems.
Some causes of battery drain.
Shorted Wires
Bad Grounds
Loose Connections
Accessories continuously plugged (ex: cell charger)
