    Cool. So, on that disco3 link, he talks about running power to the ECU using a cable he had to run himself. Did you have to do that on your LR4?

    From what I recall, no. Everything was already on the harness. But I did it more than 3 years ago so might be missing some minor details.

    sorry for necro-ing a post, but the wiring that plugs into the rear diff motor is already there? When I lifted the cab on mine, I couldn't find a connector or anything that looked like it plugged into the diff if it had the HD package. I really want to install a locking rear diff and I already checked what ECU would fit, but I'm worried about having to do the wiring to plug on the diff motor itself.
    Any info on this? Will I have to run more wires from the diff ECU to the rear diff itself?

    The wiring is mostly there. The chassis harness had all the necessary lines on mine. And the only thing I was missing is the short section that plugs into the chassis harness on one end (rectangular connector) and the diff (round connector) on the other end. I sourced that special connector and the bits from an RRS harness of ebay. They are similar(or same) as lr3, lr4.

    This is the photo of the rectangular connector on the rear left side above the exhaust pipe and above the spare tire. [​IMG]
