i am fitting a afr to my car (my99 impreza) it has three wires + - and signal. which wire do i connect the signal wire to? (it says oxygen sensor in the the instructions). i have looked at http://www.ravensblade-impreza.com but i can not see a uk99 ecu diagram. i thought it best to ask before i did some damage.
i would of searched but it is down.

btw

i have the car in bits and would like to get it back together tonight if poss.



cheers

 

anyone?

 

Donutman,
I dont know if the ecu pin layout on your car is the same as the bugeye and Im sure someone will correct if Im wrong but on the bugeye this is how it goes. You have 3 wires red being live which you can take of the back of the cigarette lighter,black being your earth which you put to one of the nuts that secures your ecu to the floor pan and either a white or green wire which is your signal wire this should be soldered onto the blue/silver striped wire which comes out of the ecu block 135 pin 17 the blue/silver striped wire is your 02 wire hope this info is of some help.

 

gussy this is what i was looking for, but i do think it is different pin on a my99 ecu.if anyone one knows the pin and colour please post it (i could do with the search function).

thanks for your help though.
