4.0 Pre-Cat: unterminated engine bay connections

[Greg M]

So while trying to identify ignition module (see other thread) I’ve discovered a number of unterminated connections.

This shows a two-cable connection beneath the distributor. Also no pipe connected to the back of the vacuum advance.



This shows a 3-pin connection buried in the valley beneath the plenum on the NS of the engine bay.

Is this “usual”...?

Thanks all ????

I'm not sure on the first pic but the second one looks like the lambda sensor connectors which you won't have being a pre cat?

The first picture intrigued me, so I went for a poke around in my engine bay.
I can’t find a waterproof connection of that type anywhere, connected or not.

The round connector if it has 2 wires it will be for aircon compressor clutch. If it was 3 wire it would be for a Lambda connection.

The connection on the back of the dizzy does not have a pipe fitted.

The 2 way black connector is also for aircon. The reason Barreti can't see it is because it is normally cable tied to the chassis below the oil filter. Again you probably haven't seen it as it gets oily then covered in road grime.

Thanks to you all.
