I ran this O2 sensor eliminator for 20k miles with no CEL or issues. I have now removed for a A/F ratio gauge and thought it would be worth it to share. You are actually modifying your existing o2 sensor by putting capacitor and resistor inline, similar to the universal ones sold on ebay for 15+ dollars, except this only cost about 3 dollars or less.
tools needed: wire cutter and strippers, soldering iron or small butane torch.
Parts needed: 1MFD capacitor (Radioshack Part#2721434)
1MEG 1/4w Resistor (Radioshack Part#2711356)
wire 18 gauge will do fine
shrink tubing
You don't have to use wire i just chose to build the harness then attach it inline
Step1: Cut two pieces of wire roughly 6 inches, strip wire in the middle of the wire to bridge the two wires using the capacitor, wrap wires of capacitor around bare wire and solder.

Step2: On either wire midways between capacitor and end of wire cut it, strip both ends and solder resistor inline.

Step3: Put shrink tubing on both legs of capacitor to isolate them from each other, then put shrink tubing over the entire resistor, then i chose to take one big piece and put it over the entire assembly for added protection. Be sure you remember where the resistor is located and which wire.

Step4: Time to connect to the O2 sensor. Cut the gray and black wire on your O2 sensor midways between the connector and the sensor. Connect the wire with the resistor inline to the black wires, resistor goes on the sensor side. Next connect the other inline with the gray wire. I used but connector with built in shrink tubing for this part or you can solder. Then tape up everything making sure all bare wire is isolated from each other.

It may not look as nice as the 40 dollar ones but you won't care when it works and you got money left on your wallet. I you put shrink tubing over the entire thing it would probably look a lot better than my tape job.
