Just had the converter stolen while rig was in storage. We had trouble finding a replacement so we just welded in a straight pipe, which works great except the engine check light is on all the time now because the O2 sensors aren't connected. Anyone know how to disable that particular sensor without affecting the other sensory systems on the engine? We don't have emissions checks in WA anymore and I see no reason to replace the converter only to have it stolen again! BTW, the cops do NADA! I hate to pollute but this gig gets expensive (I was quoted close to $2000 to replace the system correctly (if we can find the right part!)

What did your insurance company say?

You don’t have auto/rv insurance ? That’s what insurance is for and that would be a covered expense in comprehensive. Why have insurance if you don’t let it cover the large expenses?

The issue is not just the light on, without input from the O2 sensors the ECM will go into ‘default’ mode and the air / fuel mixture will be way off (far too rich) what it should be.

Your engine was designed to run with the converter in place. How much damage are you doing running without it? Hopefully you are smart enough to have insurance, use it to get the converter replaced. Or put a piece of tape over the light so you don't see it.

If the O2 sensor to the rear of the converter is the one that's not connected, it only reports to the ECM, if the converter is working or not and had no effect on the tune of the engine. If the O2 sensor forward of the converter is not connected, then you post is correct.
