This device was attached to the old muffler via a metal tube-sort of like a break line. Now its blinking a little green light.
According to what I looked up, it measures exhaust temps and fumes etc.
I figure I can do a "soft" delete and keep the connectors labeled until I'm sure the bus runs fine without it.
Wondering if anyone has had one of these, and if its safe to remove-just in case...IMG_0235.jpg
