If you're running a catless exhaust (heaven forbid), you might have a check engine light (CEL), to remedy this problem, disconnect your secondary o2 sensor #2, completely remove it and while you're at it, unplug your negative battery terminal cable (reset the ecu).
After you remove the secondary o2 sensor #2, cut the black sleeve in the middle with a razor blade, then cut the black wire wherever you desire (strip some of the black wire ends to allow proper connection to the butt connectors).
crimp the butt connectors on each ends of the black wire, make sure to tug on them to make sure they're properly crimped. Afterwards, time the rectifier diode to your desire specifications, then crimp both ends of the diode to your existing (already connected) butt connectors, tug on them to make sure they're properly crimped. Safely secure your connections with electrical tape and or heatshrink tubing. You're done, now connect the negative battery terminal to it's post, plug in your secondary o2 sensor #2.
The below pictures will help you analyze this project.
By the way, the non-fouler trick doesn't work on a completely catless exhaust (no)
