There are four wires stemming from the unit The document describes two methods for simulating an oxygen sensor to avoid check engine lights Two are red, and two are black
A Step-by-Step Guide to Understanding Ford 4 Wire O2 Sensor Wiring Diagram
The black wires connect to the original oxygen sensor’s.
Insulate cut oxygen sensor signal wire with the electrical tape
Begin by identifying each of the wires on the o2 sensor according to function (see the appendix for help). Learn how to install and use the symtech labs io2ss oxygen sensor simulator This manual covers installation types, signal. Construct an electronic o2 sensor simulator circuit to manage downstream ecu signals
By carefully following each step on how to make o2 sensor simulator—designing, assembling, testing, and installing—you.
