So turns out my URD controller was wired incorrectly.By the previous owneer. I found the Directions on what needs to be wired but its for a 2002 tacoma and my motor is out of a 96. So I found the pin configuration and cross referenced them. The only question is. i can not find the Air fuel sensor pin to the ECU. The only ones for my ECU are heated oxygen sensor 1 and 2. Any ideas?

 

the controller will not work for yours. You need a controller built for the older computers that run and primary oxygen sensor and not a A/F Guage.
