Connecting Case wires to Motherboard questions

[qazwsx16]

Hi, I'm building a computer for the first time and I need some help with connecting the case wires to my motherboard.
Case: Azza Solano 1000
Mobo: Gigabyte 890GPA-UD3H

Here is the picture of where I need to connect my wires to:

Here is the picture of the case wires:

I understand:
-speaker input
-power switch
-reset switch

I don't understand:
-Power LED(only 2 pins, but motherboard has 3 inputs[where should I input each one?])
-HDD LED(does it go into the +HD-?)
-MSG(Which one of the inputs should go into it?)
-CL(Which one of the inputs should go into it?)

In addition to that, I don't understand what this input does/go into:

If someone could help me with this, I'd really appreciate it. Thank you!

In regards to your first photo, the bottom right section (+HD-) is where you'd connect the H.D.D. LED jumper to.

MSG and CL, consult your mobo manual

In regards to the third photo, this is for your front panel USB. Plug it into one of the USB sections on your mobo

Thank you for the quick reply.
And thanks for telling me about looking in the manual.

So I found out:
I don't have a CL(Chassis Intrusion Dectector)
MSG (Message/Power/Sleed LED)- Supposedly connects to the "power status indicator"

To confirm, from the wires I've shown, I don't have anything that connects to the MSG port right?
And can you tell me where I'm supposed to connect my Power LEDs to? Since I only have 2 pins, should I just connect them to the +/- ports and leave the middle one vacant?

Thank you again.

Correct. Some cases use 2 pins, but most use 3. The middle one is empty.
