    Does anyone have a diagram of the thick cable that connects to the battery/starter/alternator?

    I seem to have misplaced mine and do not recall how it is all hooked up.

        Surprisingly unhelpful. 

        I was hoping someone with a 540i could take a look and report back.

          Trying to pull from memory of my m60 harness, which I'm not sure is the same as the m62, but there is a big battery cable that runs over the engine under the intake manifold for the alt then the other two wires were part of the engine harness which dropped down from around the front side of the drivers side valve cover.

            Just looked at mine yesterday while I was putting the engine back in the car. The cable comes from the passenger side floor, runs along the subframe, Y's off at the starter, continues along the subframe to the driver's side, and snakes up to the alternator inside of the exhaust. Hope that helps. Sorry, I couldn't get a decent picture.
