Seat 127 Workshop Manual (Electrical Section)

I would be grateful if someone could send me the workshop manual for the electrical system, as I'm restoring a Seat 127 and I'm having problems with the electrical system.
It belonged to a client who wanted to restore it but sold it to me. However, he had problems with the electrical system and it ripped out the wiring, so I have to replace the entire system to finish the restoration.
