Good day folks, I hope you can help me with a query. I have purchased an AirTech-UK bathroom extractor fan kit with LED light and adjustable timer. The previous extractor fan was fed from a shower pull cord switch and I want to connect the new extractor to it. The fan comes with a pre-wired 3-core feed cable = Blue (N), Black (L - Constant Active) and Brown (LT - Switch Active Trigger). The pull cord was previously wired as shown in the photo below. I assume the blue on the 3-core goes to the Neutral and the Black to the Live terminal, but where should I terminate the brown? Thank you.

If the shower is being turned off/on with the switch shown, then 
I have put coloured circles around the wires it joins to. But it is not normal to turn the shower on/off by the isolator, so I would have connected the fan to the lights, not the shower.

With regards the shower, it is a mixer shower, rather than an electric one so the pull cord switch operates the extractor fan only.
Neutral to fan should come from the load neutral, surely?

If it did, then fan would not over run, the black and brown, however, think I have got the wrong way around? Would do no harm, just would not overrun. But not seen instructions.
You’re right, sorry I’m being thick….
