I beleive the 01 Type R Dc2 has a 3 wire o2 sensor.
Does anyone know when installing an a\f ratio guage by autometer which wire (color) is the 02 sensor input on the ECU.

and also which (color) wire is 12v ignition switched.

Also what ground Wire is recommended?
Honda are closed here and its a public Holiday.
Thx

 

white for the O2 signal

 

Find the bigest white at the ecu

 

white wire off the o2 sensor.
12v source tap into your fuse box.
