By third I expect you mean the post cat sensor. On 96+ you have OBD2, and that rear sensor detects if the catalytic converter is functioning. If you disconnect it, you will have a code and most companies are nolonger selling simulators to eliminate that sensor. The good news is it can be programmed out.
