And it's probably a map car, so somewhere on the bulk head should be a square ish little block with a vacuum hose attached.

Thanks, yes you are correct with the map sensor.
I have attached a picture of the other sensor on the manifold, it's a single pin connector but I think it looks more like some sort of temperature sensor than a lambda?

I am currently making a decat pipe to replace the cat, I have a feeling the cat isn't factory so I'm unsure if it should/would have had one from factory
