Where do these wire connect to?

I am getting finished rebuilding my 2008 M3's engine, and I cant find where a few of these wires connect to. There are 2 wires, one on each side of the engine , about the same length. I cant find any connectors that they can hook to, so I think I may be missing something. Does anyone know what these sensors are for, and what they hook to? Thank you

Alarm I believe. That one is for the hood sensor.

Correct ^ anything before 03/2009 was pre-wired for the factory alarm and that is the hood switch connector.

hood open sensor. if you have the filter cowl covers removed, there isn't anywhere to mount it. you might have to plug in the sensor and duct tape it "shut" if you want the lock/unlock beep to work right.

Thank you! I couldn't find anywhere what these were for. Looks like I am missing the hood bonnet sensor it plugs into
