i need help with wiring the gauge.
i have a 2004 cav and i need to know which wire on the oxygen sensor is the signal wire. any help would be greatly appreciated.
thanks
I think its purple on all Js
closest o2 to the engine also
the o2 sensor should be on the exhaust manifold. Its also the purple wire, but splice the wire after the connector, so if you need to replace your o2 sensor, you dont have to re-attach the a/f wire.
