Since I drive a RAV 4.3, I cannot verify if your picture is the correct block.If you have access to the electrical manual, it should have a diagram showing the location of all the junction boxes.
The electrical diagram should also show how the pins are numbered so that you can locate pins L6 and L7 (verify by proper color as well). I expect each of the connectors plugged into the junction box is a letter of the alphabet, and then the pins are numbered within the connector.
Once you locate the proper connector, it may just have to be removed and reseated to clean off any corrosion. Spraying all the connectors with some electrical contact cleaner may also help. Be aware that some contact cleaner can melt plastic , so test before using.
If that doesn't work, then after finding the two pins, you could cut the wires, and reconnect them to another source of constant 12 volts . Perhaps splice then back to the blue/yellow wire in position I5.
Just a word of warning that this is a bit of a hack solution. If it was my RAV I would prefer to replace the damaged parts and make the RAV like new. However that solution could cost $100's. If you want to save some money then this hack is the way to go, but keep in mind that the water damage may/not continue to worsen.
