First of all, you don't need an exhaust shop or a special tool to unscrew the O2 sensor. I have swapped my cat/testpipe on 3 occasions and each time I have used an adjustable wrench without any effort required.

Secondly, there are a lot of people on here who will take your writeup word for word (just look at the NTPOG OBDII workaround – most people don't realize that cutting the wire will produce the same effect as wiring in an on/off switch). SO my recommendation is to just simiply tell people to splice in the connector however they see fit. I personally will not use a butt splice, I believe soldering is the best method but to each his own.

How did you determine the correct resistor? It's an extremely simple solution to a tremendously complicated problem, and you did it just by doing your homework – mad props dude!

I don't mean to criticise your post, I am insanely happy that you figured it out! I'm just saying that this mod will no **** take a normal person 5 minutes to complete, but you're writeup includes all these extra instructions that make it seem complicated.

For those of you with mechanical and electrical knowledge who know how to do this sort of stuff:

Parts:
1 10 Mega Ohm resistor rated at 1/4 watt or more. - Radioshack P/N 271-1365

Procedure:

1) Get under the car and disconnect the REAR O2 sensor from the socket and from the cat.

2) Splice the10 MegaOhm resistor into the grey wire.

3) Reconnect O2 sensor
