I am currently working on a 02 Impreza sport non-turbo, the wires for the upstream Lamba sensor have been pulled out of the multi plug and it has thrown the p0032 and p0031 fault codes on, we have replaced the lamba sensor, but are unsure into which holes the wires go into, the wire colours i have are,
Yellow/Red
White/Blue
Black
White
if anybody could tell as to which position into the multiplug these wire fit into it would be much appreciated thankyou for your help.
