Racing Beat Race Header 02 Wiring Kit for 06-15 MX-5

MX-5 Race Header Wiring Kit - Installation of a header on a MX-5 Miata requires the removal of the primary catalytic converter that is incorporated into the stock exhaust manifold assembly. This stock manifold assembly has been equipped with two (2) sensor positions, one sensor before the primary catalytic converter (this unit is an air/fuel ratio sensor), and the second (an oxygen sensor) behind it.

To accommodate the reinstallation of these sensors, the Racing Beat MX-5 header has been provided with two (2) sensor position fittings in the header primary tube collector. Since the oxygen sensor will now be reading the same oxygen levels as the air/fuel ratio sensor, the information that the oxygen sensor is providing to the ECU will result in an error code being triggered in the OBD II system, and the "check engine light" will illuminate.

Although the MX-5 will continue to operate normally with the light illuminated (and an error code triggered), driving with the light illuminated may prevent detection of another engine related problem that may occur during the race event.

The Racing Beat MX-5 Race Header Wiring Kit allows for the repositioning of the secondary oxygen sensor to an area behind the catalytic converter located in the mid-pipe unit of the MX-5. Once repositioned, this configuration will prevent an error code from being triggered. Relocating the oxygen sensor behind the secondary catalytic converter requires that the mid-pipe be removed from the car, a sensor hole be drilled (1/2-inch diameter) and a sensor nut be welded to the connecting pipe.

Our kit includes a stainless steel oxygen sensor mounting bung, plug, wiring extension, and step-by-step installation instructions. The wiring harness extension that we supply utilizes OEM electrical connectors and custom-made, high temperature Teflon-coated wire. (Note: This wiring extension features OEM connectors that are ONLY compatible for use with the secondary sensor.) This plug-in wire extension is hand-assembled by Racing Beat and is 100% compatible with the MX-5 factory oxygen sensor connectors.
