(IF you decided to go this route)
Here are example pics i just did real quick using paint. I hope this helps.
The YELLOW is the license plate frame.
The LIGHT BLUE are the wires.
Mount the license plate frame.
Let the wire run underneath the bumper and up to the black rubber seal..
You can peel that rubber seal off a little and tuck it underneath the seal. Then put the seal back on. It wont hurt the wires.
Run the wire underneath that plastic and into the truck.
Now using a Flathead Screwdriver, you can tuck the wires into the plastic side panels to hide it away. Keep doing that until you lead the wires all the way up into the front of the truck like these pics.
Here you can pop off those plastic door sills and tuck the wires underneath.
Same for the front. Pop off those door sill and wire it all the way up front and underneath the dash.
Once the wires are all tucked in and hidden, you can now pop off the dash bezel.
Uninstall the nav unit. Once the nav unit is out. You can look inside and look right & down... You might be able to see that you can access by the glove compartment area...
At this point, I use a coat hanger (bend it out straight like a fishing pole)....
From the dash nav hole, push that coat hanger all the way to under the glove compartment. It will make its way down there, trust me.
Once that works, tape the wires to the tip of the coat hanger and pull it back out!! The wires will then make its way UP to behind the nav unit!!
After thats done, any access wires hanging underneath the glove, etc should be tied down by using Zip Ties. Make it clean as possible. Dont let wires hanging everywhere!
This is a crappy write up, but i'm just trying to help.
