Baxi 57/4 Backboiler

[unr1lt]

Hi,

I have recently bought a house with a BAxi 57/4 BAck boiler. I had some building work done before moving in and my builder disconnected the spur and timer to get to the wall behind it.
I now need to get this wired in but am having trouble with the wiring diagram in the manual.

I have the following wires:

Brown (Live)
Blue (Neutral)
Green/Yellow (Earth??)
White (??)

Can anyone help?

need to know where the other end of the wire goes

All wires go to the Back boiler PCB under the Firefront. They terminate within an enclosed metal box.

the brown and white will more than likely permanant live and switched live, but were they disconnected from spur, timer or junction box,

One, I will guess the brown, will be a permanent live for the fire front. The other will be a switched live for the boiler. They all go into one removable terminal block on the boiler.
