At the ECM, which is to the right of the glovebox. Pin # 17, Light Green. Will show AC voltage.

Thank You for your response! I cant find this ECU module. I opened the glovebox and only thing i see is Cabin air filter compartment!

PS. What this VSS doing on amp? are you sure about that blue wire on non navigation amp?

disconnect the neg batt terminal... then with the ecm mounted in the vehicle(or held up like its mounted) unplug the 2nd harness from the top.. look at the wire side of the plug... should have #'s at each corner.. locate the # closest to 17 an count over til u locate a light green wire it should be in pin 17 if u counted properly..

Waking this thread from the dead. Looking for the speed wire on a 2009 RX350. Looking at the ECU harness the 2nd from the top, I see no light green wire, just a normal color green wire. I've search every way I know how on here and across the internet to no avail. Any help greatly appreciated!
