I need to replace the 02 sensor of my 93 wrangler 4.0L. I bought a universal fit bosch o2 sensor which has 4 wires running from it. My delema is My 02 sensor plug is melted and i cut it off. So, now i only have 4 wires running from the engine harness and i dont know which 4 wires from the engine harness to put with the 4 wires from the o2 sensor. The aftermarket o2 sensor has two white wires one gray and one black. The factory wireing from the harness is one black, one green w/red stripe, one black with blue stripe, and one black with green stripe. help.
Also does the o2 sensor have anything to do with the arternator because my charging system isnt working and i noticed the red and green wire runs to the arternator and then two the fuse box. any body can help be much appreciated.
