    Finishing up M50

    So the swap is almost done, but can someone PLEASE post a good picture of either an e36 bay that shows grounds, or an m/s5x e30. I found all of the plugs no problem but for the life of me cannot figure out what grounds go where.
    This may seem "Noobish" but this is my first e30 swap, and I cannot distinguish what grounds to the alternator, started, oil pan, etc.
    Thanks, and sorry if this is a wasted post.

    Theres a power and a ground by the battery tray on the engine harness. The engine needs to be grounded and thats basically it.

      See the red wire? That's my ground from the motor to the body.

          don't forget to ground the injectors to the block and the fuel rail to the front of the block

              How are the injectors grounded?

                sorry for shit picture, recycled from my thread - there's a grounding strap on injectors #1 and #6, typically there's a bracket setup that also connects all of them too, but I'm not running one without any issue.

                  You seem to be confusing the fuel injectors and your coil packs. ;)
