Does anyone know what pin on the early ECU is for the Lambda sensor, car has failed the MOT on lambda readings and it doesnt have a lambda sensor so im going to have to wire one in, it doesnt look like it's ever had one so i cant see any wires for it, unless it's part of the maf loom as i have a spare plug on that loom!

 

I have uploaded a pic of the ecu if it helps!

the spare plug that you have, is it a white one? If so then it is probably the cat on fire plug. The lambada sensor actually fits in the headers on the early classics on the drivers side. The wires running upto it are usually tucked up around the inside of the bumper (were on mine anyway).
