USB Power Outlet in the Dash

USB Power Outlet installed in the Dash

Part #: Blue Sea Systems Fast Charge #1045

Yes I know I have a few USB power outlets in the Jeep, but they are woefully underpowered to run and charge items like the new phones, tablets and other accessories that I mount in the Jeep on a daily basis. I have run chargers that plug into the power inverter and the other power outlets (cigar lighters), but I was tired of them popping out, coming loose, cords hanging all over the place and forgetting to turn the power inverter back on after getting out of the Jeep. So I needed a different way to plug in the items I use daily and leave those other options to the once in a while items. I needed a plug to power my Phone and tablet. Typically they would drain down using most of the options that I had available while in constant use through the day. I went looking in the marine world for a intelligent USB power outlet to match up with my phone and tablet. The old "I need more power" requirement. I picked up a Blue Sea Systems Fast Charge 4.8A Dual USB Charger from the local marine store. It had a few nice features including reduced electronic interference, over temperature protection, designed for the harsh marine environment, and a protective cap to keep the debris out (if you remember to shut it).

The Part
Looks just like your typical marine grade plug. Nice plastic housing, cover and the prongs on the bottom are labeled so you don't screw it up and have to take the dash apart again. I hooked a 9v battery up to it as an experiment and could get a decent charge going out of the outlet.

1. Remove the center dash panel. Here is a link to the instructions. Just make sure you put the screws somewhere safe. As you can see under the dash in the corner near the radio is plenty of room to install the USB power outlet.

Dash Removal

2. Drill a 1 1/8" drill into the top of the dash panel. It will be just about at the tip of the plastic support underneath.
3. Use a razor knife to trim back the plastic on the support for clearance of the retaining nut.
4. Remove the retaining nut from the USB power outlet.
5. Insert the outlet through the dash panel and install the retaining nut.
6. Connect a positive and negative wire lead to the (+) and (-) terminals on the USB power outlet. I used two push connectors covered in heat shrink tubing for the USB side and two ring connectors to connect to my dual battery system under the hood. That way I have constant power to the outlet even when the key is off. The draw wasn't enought to drain a battery after being left for 11 days, so I feel pretty confident on the parasitic draw not affecting the Jeep.
7. Run the power cable through the dash and out to the battery. You can alternatly run it to a switch. I have dual batteries and sometimes need to have devices remain powered while I am working on something in the field. The intelligent power outlet is good at power consumption and mine hasn't drained the battery yet. I did leave it parked with nothing plugged into it for 11 days and didn't have an issue.
8. Reinstall the dash and admire your new power outlet.

Common Sense and Safety should always be observed when working on your vehicle or doing modifications. Jackstands, wheel blocks, disconnecting the battery are a few of the basic safety precautions that should be used and may not be mentioned in the write ups on this site. You are responsible for your own installation, these write ups are a helpful guideline and should not be taken as an official installation instruction. My write up may be different from the kits currently out there, so alwasy double check the manufacturers installation instructions when installing anything. I try to keep the site up to date with changes that have occured as I discover them, but may not have the latest unless someone lets me know. If you feel that an install is above your capabilities after reading my write ups, I recommend getting together with a club and getting some help. Only a few times have I needed to employe some actual help from a shop to get something done. Usually welding or A/C work.
