Good day. I've read the manual how to connect o2 sensor w/ PRC ECU to PRA harness (http://www.hondata.com/techk20-ctr-o2wiring.html
)/ but I have a question.
- Connect A22 (use a T-Tap) which is unused on the UK Civic Type R harness to A2. This provides a switched 12V to the ECU to tell it that the oxygen sensor heater is receiving 12V and working.
I here understand that i shoul connect A2 to A22 so it get +12V from Ignition to emulate heater, but i don't understand where do i get the pin to put in the A22? Or should i find somewhere unused harness so i can get it there? Strange thing to be written in the manul @how to@ or i don't understand something.
Thx a lot.
