I've bought a 7 day timer

Now, wiring it in, the timer has a plug on it and 4 wires, brown, yellow, red and a grey with red stripe.
Where the original 1hour control unit has been fitted it was just wired in with bullet connectors and those wires are a different colour.
The wires that it connects into the eber wiring harness are all the same colour as the 7 day timer but it has one extra in the harness it is brown with white wire. Which is connected to the original 1 hour timer which is yellow with purple bands.
Has anybody got any wiring destrustions? Looked on the wiki but the 2 downloads for the eber control units won't download. And has anybody go any instructions for how to work the 7 day timer?
Thanks
