Where do I connect the O2 clamp 99 NB
I am finally installing my emanage and O2 clamp (getting rid of the HKS fcon mini). But I am unsure where on the factory ECU I should connect the O2 signal as the factory wiring diagram shows 3 heated oxygen sensors.
One "front" that connects into input 2C of the ECU
One "Rear" that connects into input 3J of the ECU
A second "Rear" that also shows as connecting into input 3J of the ECU
I'm trying to figure out which is which as I can only see one on the car. Any thoughts here? Maybe a couple are for intake air?
On that point my intake temp sensor is at the filter, I am thinking to move it to after the I/C, do you think that's worth while?
Lastly when they installed the HKS piggy back they cut the 2D connection on the ECU which goes to the dash lights (not sure where) and the Cruise control (which I don't have). Anyone know why it may have been disconnected? I guess I'll reconnect it anyway.
