So, Im doing a G5 (late 2005 model) case mod in which I plan to use the original front panel for the Power Button and Power LED (and other connections which I have figured out)

As you might know this is the model with the difficult front panel with no simple connection- no probelmo, I can work with it but I have become a little confused with the task of getting my motherboard to work with the original Front Panel.


Heres a diagram of the G5 front panel pinout-

01 02 03 04 05 05 06 07 08 09 10 11
12 13 14 15 15 16 17 18 19 20 21 22

Audio
USB
Firewire
Button/LED
unknown

01: Audio Left
02: Audio GND
03: Audio Right
04: ???
05: FIREWIRE GND (double)
06: USB VCC (+5V)
07: GND
08: GND
09: FIREWIRE TPB-
10: FIREWIRE TPB+
11: LED
12: Firewire FW802C IC VDDA (+3.3V)
13: ???
14: GND
15: FIREWIRE VCC (double) (+12V)
16: GND
17: USB D-
18: USB D+
19: GND
20: FIREWIRE TPA-
21: FIREWIRE TPA+

22: BUTTON


And for my motherboard-

So what I'm confused about is connecting the Power Button and Power LED from the motherboard to the front panel as on the front panel pinout there is only 1 connection for the power button and power led but on the Motherboards pinout there is 2 connections for each- how can I get them to work?



Any help on this would be great!

Thanks

I dont have experience with the late G5 front panel, but in the older ones goes like this:

-PLED+ and PWR on the mobo to Pin 11 and 22 on the front panel
-GND on the mobo to any GND pin on the front panel (notice that PLED- remains unconnected)

Thanks for that man

So, now I'm past that confusion I'm ready to solder the cables onto the contacts.

Seeing I just want the Power Button, Power LED, Audio Port and USB Port to work (no FireWire) I have made a diagram that I think will let everything work (except FireWire)

[Note: There is a deliberate double 5 as contact pads 5 and 15 are in fact double size single pads]


From what I've heard I should only need only a single GND on the front panel connected to GND on my motherboard (apart from Audio GND) for everything to function- is this correct?

Let me know if you see anything that is incorrect.


Thanks

Will - you are correct on the single ground! I run the G5 Resource Page at G5Modders.com - would you mind if I add this to the Front Panel informational page? We don't have much about the late '05 G5 but (and you're evidence of this) I know there are people out there that could benefit from your knowledge! Let me know if this diagram worked for you and whether you would be ok with that (you would be credited!)

Thanks!
