On my car, the o2 sensor has four wires on it. Im ordering a simulator like the one up there ^ (probably the Universal one). What does it mean by dual/single output?

On the install page: http://www.o2simulator.com/28301/index.html

It shows one signal, one Power, and one ground, and then an extra wire with no labeling on it. Could this be the 2nd output (the first output being the signal wire)?

 

Well I was gonna say go with Casper electronics O2 sim, they are plug n play and specific or vehicle years... but apparently they've decided to discontinue the sale, support, etc, etc. of the O2 sims. The second wire you are talking about does have a label, it's an extra signal wire, but the O2 sensor doesn't have 2 signal wires, one wire heats the O2 sensor up for better use and longer life.

 

so i should just get the Single output simulator, wire it in there, and leave the heat wire alone?


Edit: But first i need to know which wire is which? Anybody know? Damn i should just buy a manual eh?

And one more thing, i already extended the wires from the secondary o2 sensor into my engine bay. There might be a chance that something went wrong with extending them, so do i actually NEED the heat wire? Or can i just cut it? Really, as long as the o2 simulator is getting power and the Signal wire from the o2 simulator to the ECU is correctly spliced, it will work right?

 

This could get ugly... get the manual. I need to get me one myself

 

Wire Guide and Install Instructions. "What is the difference between Single and Dual output o2 simulator?

Practically none. Dual output o2sim has two Signal wires. Signal wires are shorted inside the unit." it's simply if you have two cats you need the dual outputs.
