Installation and configuration
Read over this entire document before beginning installation!
Securely mount the controller to a location within 36 inches of the oxygen sensor
location. The controller may be located inside the car or in the engine compartment.
The controller unit is water-resistant, but it is not waterproof. If you are mounting
the controller in the engine compartment, select a location with minimal exposure to
water as a safeguard.
Route the wiring well away from any moving parts or extreme heat sources like
header pipes, etc. Connect the harness as per the diagrams in this manual.
If your exhaust system doesn’t already have a fitting in place for an oxygen sensor,
one must be welded in place. A fitting has been included with the kit. If you need to
weld this fitting in place, be certain to weld all the way around the outside of the
fitting to prevent any air leaks. The optimum location for the oxygen sensor is in the
collector of a header or exhaust manifold. Put anti-seize on threads and be careful
not to get any on the element of the sensor.
Note: For 77063 users, 2 oxygen
sensors and 2 oxygen sensor fittings are included in the kit. Each fitting
should be properly welded into each side of the exhaust system.
In turbocharged applications, the sensor must be in the downpipe, not in the
collector. The high heat and pressure found in the collector of a turbocharged car
will impact the accuracy of the sensor and will drastically reduce the life expectancy
of the sensor.
In any application, avoid installing the sensor in the short-side radius of a bend in
the exhaust tubing. Also, try to mount the sensor in a location that offers some
protection from damage caused by debris or other objects in the roadway.
