O2 Simulator

I have a 2005 5.3L Silverado and I want to install a o2 simulator...What colour(color) are the wires on the sensor. The Signal wire? The +12 wire? The ground? and Heater Signal wire? I've looked on the net and asked a guy at a dealer ship. No help there. Thanks

what is a simulator? Is it also called a 02Sim? That is used to fool the computer into thinking that there is an 02 Sensor there even though you have removed the cats? If it is usaly you order the one for your application and then plug it in.

They don't make an O2Sim for a 2005 silverado they only go up to 2003 then somethings different and it won't work. And Sim is short for Simulator.
