    This is a public service announcement for anyone who wants to or has removed the downstream cats on their 2nd gen Tacoma… (2009 4.0 V6 TRD Off-Road) Removing these, at least for me, threw a CEL immediately. So after a few months of research and seeing probably 10 different ways of rigging your O2 Sensor I have found this is the best way, at least for this generation of Tacoma.

    a single resistor inline with the O2 sensor’s Blue wire worked for my rig… the coming months will tell of course and I will keep you all updated.

    Here is the link to Amazon for the resistor pack I soldered in-line (1Mohm 1/2w resistor)

    I hope this post finds someone that can use it!
