Hi all,

Trying to wire an aem uego wideband into the ecu for the O2 feedback.

I'm reading everywhere that I should tap the c16 pin on the ecu for the O2 sensor signal and I can't seem to find it on my 06.

I'm referencing this post: https://honda-tech.com/forums/honda-.../#post31033706

Looks like the 06+ is different? Is it the A28 or A31 pin I want?

i don't know which exact one is the C connector, I've read conflicting info here that it's the blue connector into the ecu but I don't have one?

Please help! Thanks!

In the electrical manual for a 2008 it appears pin A31 is AF input (+) Red wire. And A28 is AF ground (-) Red/Yellow wire.

O2 sensor input should go to A31, A28 is a dedicated ground for the AF sensor.

My instinct says both pins be connected directly to the sensor for the most accurate readings.
However I do not have real-world experience in an 06+ or knowledge of your build to say for certain if both need to be connected.

I received conflicting information in the Forced Induction forum. I referred to the Hondata help instructions and wired the input signal from the o2 into E1 pin - ECT2 input I believe. Car isn't back together yet but we'll see how it does! Haha.

As per Hondata, I'll have to disable the ECT2 input in the ECU and point the o2 sensor to read the voltage from that input instead within the flashpro software.

Any update to this? I had that white wire connected to the ect2 wire and also tried the eld wire. Both would transmit data to the pc but flashpro wouldn't allow it to be used. I'm not sure what the problem is.
