I have searched far and wide online and am unable to find where the network door multiplex is located on the driver side. I can find the part, but no replacement info. I have pulled both driver side door panels and do not see it. Part # is 89222-0E012, pic attached.
Anyone have more info on it? Is there more than one on driver side? What little i have found seems to indicate its just one.
I have no idea what that is but knowing Toyota/Lexus, a part of that size and shape is typically behind the dash, can't see it within a door nor did I see it when I did my remote start install. Could be on the driver or passenger side. My bet is on the passenger side next to the ECU, which is right behind the glovebox to the far top right.
I think we're all missing a crucial question... what is your purpose for wanting to replace this? If if's because your windows and or sunroof aren't working as expected, you have to re-learn them. This happens anytime the battery is disconnected.
Thanks RedGemini, those images from his post are exactly what I needed. This multiplexor was suggested by mechanic as the culprit of a random parasitic drain.
