Front Pannel Connectos To Motherboard_Positive and Negative?

Hi, i am building my New PC, and i have to connect the CASE Front Pannel Connectors to the Motherboard Front Panel Header.

All the cables are black, and only the POWER LED connectors are 2 separate cables each one named as + Positive and - Negative... The other cables as POWER SWITCH, HARD DRIVE ACTIVITY LED, and RESET SWITCH are 2 Joint cables each and they dont show which side is the POSITIVE and which is the NEGATIVE...

The Case is a CORSAIR 350D. The Motherboard is a Gigabyte Z87MX-D3H

How can i find out which hole is the Positive and Negative on each cable? Does it really matter? What if i connect it Positive with Negative and vice versa?

Thanks. I just noticed that the Double Connectors (POWER SWITCH, HARD DRIVE ACTIVITY LED, and RESET SWITCH) have a small TRIANGLE on the back, towards a side. Maybe this indicates the Positive or Negative? Which one will it be?

I am unable to find the 350D manual ONLINE (it did not came printed either). But i found the 800D manual, and there it says the following:

Pin 1 is indicated by a small arrow on the connector

What or which is PIN 1 then?

This is a Picture of my Case Connectors... (The small triangles are on the back, so they dont show in this image)

Sorry, here is the link to the CABLES PHOTO: 350d Case Front Panel Connectors

So i will do as you say, and i will connect them and test. IF they dont work, i just switch...
I was afraid i could damage the components if i connected them incorrectly...

I have built over 50 systems and have used trial and error to get these front panel connections right.

I have never damaged the motherboard or anything else for that matter by connecting these back to front.

Hope it helps

Often the best way to attach images here is so they display inline... that's done with the Insert Image button on the editor's toolbar, by the way.

Thanks for all your help. I took all your advice and the front panel seems to be connected the right way.

I Can assure now that the small TRIANGLE on each cable means POSITIVE.
