Hi guys, I'm doing an alternator swap on my 300tdi from a broken standard 100amp model to a 120 amp fully working, I've got two questions for you could be a really simple answer if I'm on the right track

is the wiring as follows as they are both diffrent layouts
Red = B+
Blue = D+
white = W

2nd question will I have to upgrade my Red (circled) wire for the extra 20amps, I know a new end will need crimping as it's barely making a connection at the moment if so can I just run a new wire directly to the battery.

many thanks
lewis
