o2 question

*SwaintaN* · 08-25-2008, 11:17 PM

ok, i need to know which wire from which o2 sensor is the sending wire, one that goes back to the comp and says if its to rich or not. if it works, this will be the second half of the HHO install, for an EFIE and im hoping to hell it works like it says! keep you updated if it does, til then I need help on knowing which wire is which.

Use your voltmeter to test each wire. 2 are for O2 heater(Grey) the other 2 are ground and output.

Its easier from underneath to get to the wires.

Unless your truck is lowered, you should be able to slide under the truck and access them.

Use a pair of ramps on the front tires.

Still no other way expect for a volt meter? Will the volt be higher or lower with the sending wire?

If you eliminate the gray wires from testing. All you have to do is then find the ground wire with a continuity tester. That leaves you the + voltage signal cable.
