This results in tripping a signal from the right rear (sliding) door trigger instead of the AUTOLIGHT signal.<br /> <br /> The problem applies to the installation of this T-harness on all 3rd gen. Siennas. The correct info on the Body ECU white 30 pin plug wiring can be found here: <a href="https://www.the12volt.com/installbay/printer_friendly_posts.asp?fid=3&amp;tid=122207" rel="nofollow">https://www.the12volt.com/installbay/printer_friendly_posts.asp?fid=3&amp;tid=122207</a><br /> <br /> To the contrast, the wiring diagram on the installation guide without this low-current T-harness is correct (Guide #72751), the AUTOLIGHT signal being taken from a different connector (on the steering column).
