Hi,

Does anyone know which is the wire on the o2 sensor that has 0-1 volts coming from it...??? ie the signal for my AFR gauge....!!

I have a 1995 WRX and just need to know what colour wire i need to tap into...

Thanks

Dan

 

anyone...?????

 

i have been informed by every tuner that i have spoken to that it is best to connect the afr wire as close to the ecu as poss...
Rob
p.s. IIRC the wire needed on the ecu is the bottom row 4th/5th wire in.. it is white with silver rings every 1-2cm along it.
If you have a multimeter you can test that you have the right one.
Oh by the way, you wont get much of a reading for a min or so until it heats up...

 

Hi,

will this be the same for my 1995 wrx i.e the wire colour....

Where is the o2 sensor on my scoob cant see it from the engine bay is it hidden somewhere..??

Thanks

Dan

 

Should be on the downpipe.

 

Just to say its not in the downpipe, its in the headers drivers side for that MY.

The ECU O2 sensor input for your car is B43 Pin 6 (see below)

hi dan,your signal wire from your lambda sensor is the white one,you should have a red and a black too.
