Yes, that's correct. "Signal Hi" is what you want. "Signal lo" is the ground reference from the ECU.

RE: O4 Chevy Silverado oxygen sensor
heavyone71,

So how did that work for you. Do you have your system up and running? I also have an 04 Chevy 5 liter v8 and want to install a system. Besides a booster(generator) and O2 sensor adjuster what else is in you system. Can you send me your details and results. Just trying to get started and designing my system.

Thanks
