Re: wideband wiring (roachsboosted16)
it would help to know what wideband and tuning program you have.....
typically the widebands will have 0-1volt and 0-5volt inputs. The 5volt wire goes to the primary o2 sensor if using crome. (you must scale the wideband to read 0-3.8 volts). If you are using a program which can utilize the 5volts, wire it to ELD, EGR...etc.

Do you have a PLX SM-AFR module or just the wide band LSU4.2 Bosch O2 sensor itself?
If you have a complete PLX system there are manuals on there website.
Check them out.

If you do not have a wide band controller or module to run your LSU4.2 WB O2 it's not worth the hassle of hardwiring the WB O2 into a narrow band driven EMS.
