i have not gone under the car yet, but would like some direction before i get going. i'm going to install a test pipe and was wondering where i install the little simulator. i'm guessing it's close to the o2 sensor down there, but just want to verify if i install it close to the o2 sensor or not. thanks.

 

you are going to need 2 12"+ extensions with the simulator. (unless the simulator has long wires coming off it. We have 2 sensors and where they conect is atleast a foot and a half to 2 feet apart.. once you get them all you need to di is conec them to the simulator and the plugs on the car

 

oh. i thought the o2 simulator was only used for the second sensor, the one in the cat. thanks for the info. are there any diy's by chance you know of? thanks.
