Hey guys,
My LC-1 just came today and I wanted to ask a quick question.
I read through the instructions on their website and understand how to wire it.

My only question was about the grounding. Has anyone just used the existing O2 sensor wiring to hook the sensor up?

I know it has a heater wire, signal wire and ground.
I'm just curious as this would make it easier to install and cleaner.

Thanks

 

I ran it that way with no issues at all.

 

Cool, I'm going to wire it into my jumper harness where the factory o2 wires are.

 

I had trouble with the lc1. the controller fried once when my ground pack came loose at the thermostat, then the second controller fried shortly after installing it for an unknown reason. Switched to aem, no issues since.

 

Cool story!

 

Im guessing you dont like my story? Actually, it wasnt very cool at all, it was frustrating, especially trying to figure out why it stopped working all the sudden. I did read several times that the best place to put all the grounds is at the thermostat, because the ecu is grounded there. I hope the op has better luck using it than I. I like the gauge face itself of this wideband. Looks nice.
