    2011 d4 3.0sdv6 3.6tdv8 conversion

    Hi there, my 3.0 sdv6 crankshaft has snapped and I'm going to put a 3.6 tdv8 engine in to my d4.

    Ive bought a complete 2010 l320 range rover sport and plan on swapping the gearbox and engine loom over onto my d4 aswell as the ecu but I want to keep my 8 speed zf8hp gearbox.

    The l320 6 speed gearbox loom is different to the d4 8 speed loom especially on the round connector that goes into to the gearbox. I have found a wiring diagram for the d4 to trace wires but I can't find one for a 2010 facelift l320 3.6 tdv8. I believe they both run the same canbus system since they updated it in 2010 on the l320. Could anyone supply me with a wiring diagram for a 2010 range rover sport l320 tdv8? Or does anyone know what wires do what just on the round connector that goes into the gearbox?

    I know on my d4 there's only 7 wires, 4 are for canbus 1 is earth and 2 are various live wires but the 6 speed l320 has a lot more wires on that connector and I can not find a diagram. Thank you, I am well aware how difficult this conversion may be so negative comments are welcome but will be ignored.

    Why do you need to swap gearbox looms?
    I've already supplied the 6-speed's wiring diagram in another thread of yours.

    I read on the Defender 2 UK forum that someone has put the new ingenium D350 engine and trans into a D4. Not sure of any details, but that would be a hard conversion imho. I think you're on the right track. Another option would be the 4.4l v8 from the RRS, they share more than a few parts with the Disco's.

    Talk to Cambo and Old Jaguar - he has done a bunch of 6sp >> 8sp conversions for the D4, so may be able to give some guidance. Or sell some
