I'm Looking for the Electric wiring diag. for emission control for TOYOTA Hilux model 2004 . Im suffering from excesive fuel consumption . with greatfull thanks for your interast in this query .

My understanding is your vehicle is the international version of the Toyota 4Runner..

The diagrams should be the same..

Here is a link to one..

But perhaps you can search the internet for info on the 4-runner and find what you want..
