Removing bedroom light pull advise

[Liv91]

Hi, looking for some advise -

I am currently renovating an Edwardian terrace and want to remove a bedroom light pull that has been installed in addition to the switch at some point.

I have done some reading and have a fair idea of how I’m supposed to do it. I have removed the pull and pulled the wires through to the loft. My plan is to then join them in a Wago box. Only thing is I have a wire with 4 cores and a wire with 3 cores.

Can anyone advise which should join with which?

Any help is much appreciated!

The only colour which has only one use is green/yellow, which is only used for an earth.

It seems likely the pull cord is part of a two way wiring system. But to remove you need to work out what each wire does.

I have a problem I would expect not counting earths either a three core on it's own, or a three and two core, your picture shows a three core and single core, so it would need some testing and further investigation.

To be sure we are giving the correct info, can you send a picture or confirm exactly what is at the wall switch?

(Might save time in the long-run.)

Not counting earths, there is a three-core and a two-core.

It looks to me like a two-way system wrongly wired.

Is the reason you want to remove the switch because the system doesn't work properly?

Should’ve gone to Specsavers

That would work - if at the other switch there is a brown in common, and grey and black in L1 and L2.

It's the old fashioned method, where you use a connector block or porcelain dog cock it's really old.

Ah yes. Thanks.

Two green/yellow together
Two brown together
Blue with brown sleeve to black with brown sleeve
Grey with brown sleeve in it's own terminal not connected to anything else

An alternative is to remove the 3 core & earth completely at the other switch, and connect the 2 core & earth directly to the other switch.

Thanks so much for your help so far guys.

To confirm, the black, grey, brown, earth comes from the switch and the blue, brown earth goes from the pull cord to the light rose.
