Lower Dashboard, 12V socket and Wiring Cleanup

I contacted the USB hub vendor for assistance why it wasn't delivering power to the Droid Bionic, but got nothing back.  I decided to install a 12V socket under the dashboard for two reasons.  First, I know it will work.  Second, depending on the 12V charger plug, it will deliver more than the 900ma I was hoping for with the USB hub.  I had one lying around rated for 1A (1000ma) output.  Hopefully that will be able to keep up with the power draw when the phone is running my PakTrakr app, GPS and Bluetooth.

I mounted the 12V socket and wired it to an unswitched fuse in the new fuse block.  You can see the 12V charger plugged into the socket on the left side.  This leaves me with 3 USB power ports for future use.


With all of the new wiring done, I tidied up under the dashboard.  I put wire loom on all of the wire groupings I created and zip-tied everything into place and tight.

I then moved to the lower dashboard.  The only change here is to bolt in the mounting frame for the two Electro Auto instruments.  That went in nicely, then I screwed the lower dashboard into the dashboard frame.  Mounted the instruments into the frame and wired them up.  I then stuck in the right and left vents and tightened them down.

My to-do list is getting very short!  To finish off the interior, I just have to install the glove compartment and refurbish the upper dashboard.

PakTrakr Next Steps and USB Device Power

With the PakTrakr remotes installed and tested, it's time to add the current sensor.  The opening in the sensor is not big enough to pass a lug or battery cable through, so I used the copper bar provided in the kit, and bolted it in.  The sensor's data cable runs through the firewall and in behind the dashboard for its ultimate home in the PakTrakr dashboard display unit.


With that done, it's time to clean up the wiring.  Each PakTrakr remote has a generous amount of wire to run to each battery.  With the help of some butt terminals and zip ties, the wiring is now nice and tidy.

Here's the front battery pack.


Here's the mid battery pack:


Here's the rear battery pack:


and here are the saddlebags:


The final component to go into the PakTrakr system is the serial port output cable.  I've got it lined up here next to the serial port Bluetooth transmitter device which provides the path to the Bluetooth receiver in my Droid Bionic.  This delivers the data stream from the PakTrakr to the Android app I'm desperately trying to finish up, which will run in the phone as I drive down the road.


The Bluetooth transmitter needs power and conveniently it will take power via a USB cable.  My Droid Bionic also will take power via a USB cable.  I also plan to mount a GoPro video camera which recharges with USB power.  See a pattern developing?  With three USB devices, I looked around for a USB hub with 4 ports (for future use or passenger's device) and high-power delivery a la USB 3 at 900ma.  It has to take 12VDC so I don't have to have a separate power regulator.  I came on this sweet device, the awkwardly-named USBG-3X4M.  Notice the green 12V power connector.


Here it is mounted up under the dashboard.  The BlueTooth transmitter powers up no problem, but my Droid Bionic won't recognize any power coming from the unit, no matter what USB cable or port I try.  I've emailed the vendor and hopefully they'll have a suggestion.
