Parts:
1 uF capacitor
1Megaohm resistor
Tools:
soldering iron
wire cutters/strippers
solder
heat shrinks tubing
Tape
piece of hose or conduit
zip ties
rtv silicone
Wire the resistor in series on the signal wire out of the o2 sensor; that means cut the wire and solder in the resistor inline (gray wire) between the sensor body and the plug.
Wire the capacitor in parallel with the sensor, that means solder the capacitor from the signal (gray) wire to the ground wire (black wire). No need to cut the ground wire just cut off some insulation.
Connect the capacitor to the plug side of the solder joint where you hooked in the resistor on the signal (gray) wire.
After cutting the gray wire slide on a piece of heat shrink tubing on one of the wires. After soldering the two parts onto the sensor harness slide up the tubing to cover as much of the parts as possible.
Shrink it with heat. Tape any remaining exposed wires. Put the hose or conduit around the parts and taped wires. Zip tie it tight. Put RTV sealant along the seam and at the ends of the hose/conduit to seal it from moisture.
Repeat for the other side.
Now these O2 sensors are permanently set up to eliminate the MIL and they plug in normally.
Don't cut the two white sensor wires, those are the heater circuit.
** Oh yeah, the insulation on the wires is tough, Teflon insulation. The RTV sticks well but not much else does. THe wires also take a lot of heat for the solder to stick well so make sure the joints are good. Not hard, just pay attention to detail. You don't necessarily need any heat shrink tubing just use tape if you are going to seal the hose/conduit with RTV silicone afterwards.**
