Fellow E70 owners!

Please, anyone who installed the OEM hitch harness and AHM module, I am trying to understand how the AHM and the hitch harness connects to the E70. I recently bought a used OEM hitch and AHM module for the X5, but the harness connector to the AHM had been cut off. Since there is only one port on the AHM I take it that the harness has more than one connector, the one to the module and another to the vehicle, presumably the CAN bus. The harness did come with one small connector that look like it connects to the PDC sensor but I don't understand why that would be the case. Soon I should get delivery of a plug connecting to the AHM, I bought a used pigtail but I realized that I am possibly still missing a plug to connect to the bus. Anyone who installed the OEM kit, it would be really helpful if you could post or PM me some pictures of the various items the harness connects to.
