Thank you Neilhart. This clears a lot. I also suspected that power was missing from those, so it must be handled otherwise.

Yes I have a Apple SATA shelf harness here in front of me. The power to the drives is via the 8 pin Molex. Some people have found the mating connector on Mouser's web site and build out a power solution that way. I cut off the 8 pin Molex and attached a PC style harness (solder splice).

Mac Pro - Front Panel woes... And solution!

I had so much good luck with information posted on the Aquamac site that I didn't think I'd have any problems with the front panel pinouts...

However, after wiring to the Aquamac diagram, I found that neither of my USB ports worked... After much tinkering, it looks like the +5 volt supply for the two USB ports was all that was missing. So, here is my revised version of the Front Panel wiring diagram.

Note that the 2 "lower front" pins power the individual USB ports. The "frontmost" pin powers the upper USB port and the pin next to it powers the lower USB port. I just twisted all 3 of the +5 volt lines together and spliced them into a single +5 volt line from the SATA power connector.

The "green" line/wire provides power for the front panel white LED (power on).

The "purple" line/wire provides the Power button signal for the motherboard. Neither the LED or Power button require a ground line as long as the "black" line/wire is connected properly to the system ground.

What is missing from this diagram is the "SATA" cable that is used to carry the USB signals to the motherboard. Many of the other threads out there about hacking the front panel talk about use of SATA/eSATA to encapsulate USB... Well, that's just garbage. Not sure why Apple chose to use this "standard" connector in a non-standard approach, but it probably came down to cost. These connectors are used so widely that they are probably very cheap. While it happens to have a SATA connector on it, it is simply used as a piece of shielded 2 pair cable (happens to NOT be twisted pair). I used a "left" angle black SATA cable (bought at NewEgg).

This cable has the angled connector in the opposite direction from the "standard" right-angle SATA connector (I guess that's why people call it a Left-angle connector??). It is the proper orientation for the cable header and points towards the motherboard.

Cut off the "straight" end of the cable and either splice on an existing USB header connector or buy a new USB header connector and attach to the end of the USB cable (that's what I did).

I did use Aquamac's wiring diagram for this cable:

Works great!

I have no Firewire ports on my motherboard and don't really see a need for them, so I won't be connecting those any time soon.

When I figure out the audio header, I'll post that too...

Hello!

I am working on getting the front panel of an old Mac Pro tower to work with my little NUC Hackintosh. I have the pinout of my front panel board, I have already followed your above guide for connecting the left handed SATA to the usb 2.0 header but wanted to know what the 12v power was for and if it was possible to make a pinout to just go from the front panel to my front panel header on the NUC board.

Here is the pinout on my NUC board:

Any help would be much appreciated!

Your mod is going well. I have the same motherboard and case and have basically finished my G5 build. Like the idea of using the PC standoffs. Did you leave the threaded section on? I've reused the G5 standoffs on both my G5 mods. I based my build on Mahdi0's lazy G5 mod in the customization forum. However, I decided to turn the PS fan down, so I cut a section out in the shelf for the fan. Looks good, but I lost the last two hard drive bays.

Look forward to additional pics and posts on your mod.

Sorry to drag up an old thread but since you cut on the drive bay bracket, maybe you can help me. How do get that bracket out? The one that the drive sleds attach to (2010 mac pro). In my case, I just need to take it out and make the hole for cables bigger, then put it back in.

I just do not recall the details now. You do need to remove the sliding latch at the front of the top shelf... search for detail on this and the same steps apply to a G5 Power Mac. Then remove all of the round nuts at the back of the shelf to the rear/left panel. There are also nuts or screws that need to be removed at the center fan bracket.

I'm having the same issue now in late 2017. So much time has passed that all of the images aren't showing up. I can't find the original diagram anywhere or any photos whatsoever of any solutions. Is there any possible way you could help a newbie out? :)
