viewtopic.php?f=11&t=4011this thread reckons the wiring loom is the same across all models the wiring will be on the back of the dash plug.
http://www.tuningconcepts.com/Cars/Hilu ... iagram.pdfpage 76 says its a b-w wire connected to terminal A4 on the enigine ecu
page 77 says the b-w goes to A7 on the combo meter
Id start looking at the back of the combo meter
how to prove its the right wire before connecting? cross fingers
How do I know I'm showing you the right wiring diagram I don't unfortunately.
weather the aftermarket taco will work with the toyato factory signal what ever it is???????????
good luck .
