Electric Diagram of Renault Express 1.9 Diesel

Hello everyone.
I need the electrical diagram of the Renault Express Diesel (F8Q). I bought this truck recently. The alarm system installed practically destroyed the electrical installation that became a bunch of cut cables, spliced ​​and full of relays. I would thank whoever possesses the electrical diagram, upload it to the site or send it to my email, privately, to definitely solve the problem. Thanks again.
