I have an 01 WS6 was wondering if I can use the signal wire at the ecu? Or should I go to the o2 sensor and if at o2 sensor which one, I dont want to use a pigtail and will hard wire.

Will the ECU way work?

Tap into the signal wire going to the ecm. The gauge reads the same signal as the ecm.

that is on pin 66
PPL wire

I want it on this sensor correct HO2S High Signal [Bank 2 Sensor 1]

or

pin 69
PPL/WHT wire
HO2S High Signal [Bank 1 Sensor 1]

Unless you install a wideband sensor. The gauge will be useless.

Just one wideband sensor, or two? In place of the stock sensors or install new bung(s) for the wideband sensor(s)? I've heard some say you must always retain the stock narrowband sensors and install new bungs for the widebands...Others say replace the stock ones with the widebands. I've got widebands sitting in the box and was going to use them once I get back from vacation...until war broke out not long after I got here and extended my 'vacation' a few weeks.

Leave the narrow band sensor alone for normal driving.

Most use one wideband. Some put it in the I-Pipe.

I have mine in the passenger side rear O2 bung.

agreed. dont try to use it with the NB o2s. Your readings will be wrong. Get a WB, then hook the gauge up to that. I know the LC1 has instructions on how to wire it up. You can download them from innovates website.
