The factory service manual for New Holland T4.55, T4.65 and T4.75 PowerStar tractors, Tier 4B (Final) units from PIN ZDAH00008 and up.
It runs from the engine and dual clutch through the 8x8 and 12x12 mechanical shuttle transmissions (plus the 20x20 creeper), 4WD, both axles, PTO, brakes, hydraulics, steering, cab climate control, the front loader and bodywork.
The electrical section is the big one: a full set of wiring diagrams (p901-1820) with a how-to-read guide at p928. You get real numbers, not filler: clutch housing screws 117-129 N·m (p98), driven plate wear limit 10.4-10.6 mm (p99), lift pump flow 45 l/min (p576), fluid capacities on p19.
