On the 94 and up trucks there are two O2 sensors, one before and one after the Cat.
I know that if you only disconnect the second sensor, that the Check Engine idiot light comes on.

I also have heard that someone makes a resistor plug-in type deal so that you can do away with the second sensor.

Does anyone know who makes this and what is the name of it??
Thanks for your help...
