Install o2 simulator AND create heater circuit simulator. Tools required: |
|
Parts needed: o2 simulator ( www.o2simulator.com ) |
Step 1 Cut connector plug off the old o2 sensor. Since o2 sensors are quite expensive I used one that was no longer good. If you are sure you are never going to need your secondary o2 sensor again then be my guest and cut away. Though, do cut wisely. Leave at least 2 inches of wire on the connector, you never know if you might make a mistake.. or two. |
Step 3 I chose to use an old o2 sensor harness plug to make everything neat however everything may also be wired directly to the cars wiring harness. For Honda 96 - 00 the harness colors are as follows: White/Red-Sensor wire, Green/Yellow-Sensor ground, and Black/Yellow-+12v heater. If you plan to use the o2 sensor plug such as I did, the picture shows the polarity of the two black heater wires that are attached to the stock o2 sensor. |
Although the resistor can be wired in either direction, +12 volts is needed for the o2 simulator and this is the easiest place to get it, as the next few steps will show. Note that o2 sensors that ARE NOT oem will probably have different colors for their wires. Follow this diagram. |
The o2 simulator First I wired up the o2 simulator to the + and - signal wires. Green is negative signal and white is positive signal. This is equal to black and white on the o2 simulator. The red wire is the +12v power wire for the o2 simulator and will need to be hooked to the +12v heater circuit wire as shown in the previous picture. |
