G-Wiz Heated Seat connections

Hi everyone,

I want to install Heated seats on My G-Wiz but I can’t seem to find the connections for it on the car. I know that there should be 2 connectors coming from the same place as the battery cables into the battery compartment. I found the smaller one (round one) but there should also be a second RED/Black connector for the power. It seems mine doesn’t have that.

Is it at all possible to ask if anyone knows where that power would be coming from in the back inside the electronics? A picture would really help.
