I bought a 2003 A4 3.0 V6 Quattro with a DSG gearbox for £800, the original engine snapped its timing belt and put a conrod through the block so i had to buy another engine, but I've put it in, however the car will not start

The neutral safety switch for the gearbox has been damaged, the plug on it and the socket on the cars loom have been burnt, where is the best place to get a wiring diagram for this so i can try and solder the wires together. At the moment the colours do not match so i would need a wiring diagram. I don't mind buying one but would like some advice on where the best source of one is.

Thanks
