i want to put the guage straight to the ecu and i went to the honda dealer and asked them if i could look at an electric book for my 97 and the primary o2 sensor is 6a on the ecu. can i tap that or do i have to find the hihg signal on my o2 sensor on my downpipe and tap that? can anyone help? i just dont want to **** the guage cause it says if installed wrong it will **** it up

 

THe correct wire should be D7(white)

 

are you sure? cause i think d7 or 17 was the secondary o2 sensor? it's for my 97 EX . is anyone possitive?

 

yes 100% sure.

There is no D17.
And A6 is the PHO2 heater circuit.

 

thanks alot!!! im gonna try it now
