I was looking at the LM-1 basic kit and the LSU-4.2 O2. Im real interested in getting a wb o2 but after several searches i still cant figure where all 5 wires go. Sorry if this is a repeat and i would be glad for some searches. Can i use the wb with T-Pro 4.0? Where do i hook up the 5 wires?

I do not have the LM-1, but do have the zt-2, from zeitronix.

One wire will be 12 volt power, another will be ground. I have one running to the distributor reference pulse (for RPM's), one to the TPS signal, and one from the MAP sensor.

I spliced in the harness right before it goes into the ECM. You will need a wiring diagram to be able to pick the correct wires.

The wb will not show up in TP, without a lot of work. Unless you use the wb in place of the stock nb and feed the signal back to the ECM.


Hope this helps some.

Just to clarify, the 5 -wires from the O2 sensor itself go to the control box, not to your ecm. The wires from the control box should be clearly labeled in the instructions that came with it.

You probably already knew this, but the post sounded like you were wanting to hook the sensor directly up to your ecm.
