Parasitic drain?

Hello, it looks like the BCM has three main connectors on this vehicle, is that correct? And can you give us the wire colors for the ones you're finding a drain on? Also how are you checking for a draw? Amp clamp, meter in series, etc?
Here are the 3 BCM connectors.
I'll assume you're meaning connector C3.
So depending on which wire colors you have in that connector will determine which of the two different connectors your vehicle has. I do see in the 2nd C3 connector some door switches which could be stuck on and keep the BCM awake after the vehicle is off causing a drain on the battery, do you notice any lights staying on or interior lights that don't work anymore? 700ma sounds about what switches might draw, relays themselves draw around 250ma, and it's not enough for a light bulb, unless it's an LED. But knowing what the wire colors are will help narrow down the possibilities.
