Wideband O2 sensor only for ms2??
but the one that i have is a f.a.s.t. bosch with 5 wires..it has a pump that pumps air through the sensor, not sure if it will work without the pump wired correctly and the fast needs to be turned on every time before use, i'm wanting to use just a wb sensor to feed the ms2 but don't know which one to get? I want a 4 wire wb sensor but can't seem to find a part number for one?
Thank you for your time!
