I have been meaning to post this for sometime. I have been using this setup for about 4 months now and its working great. I used lots of information from this forum to get this done. Many thanks to those who came before me. Hope this helps someone else out in the future. I originally made this as a set of slides for my ham club so I had to reformat a little for this format.

Way easier than I thought. Many thanks to DaPersianRug for the info he provided. It helped alot
Steps
Research online
– T4R Forum for hints from others
DaPersianRug(wiring)
Small Footprint CB/HAM Radio Install
Antman(wheel well storage)
Rear Wheel Well Storage?
Scout out locations
– Radio body (rear driver wheel well – open, battery side)
– Speaker (under passenger seat attached to mount)
– Antenna (hatch driver side by radio)
– Power (to the battery)
– Head unit (by cubby hole)
Remove wheel well covers
– Pry up, break tabs, cut off broken parts
Remove trim/weather stripping exposing wire tray
– Pry up carefully
Run battery cable through firewall
– Existing port not easily passed through
– Nipple cut open to feed through
– Wires passed and sealed with silicon
Fabricate radio mounting bracket
Found that in the driver side wheel well there was a great place to attach but needed a way to hold radio out where more space existed.
– Cut aluminum
– Bend aluminum(needed angle to sit correctly/vertically)
– Drill mounts for frame and radio
Fish Wires (coat hanger and electrical tape)
Nothing special. Just a coat hanger, tape, and patience.
– power wires to back
– extension wire to front
– speaker cable around to right side and to passenger seat
Mount speaker to small screw mount
– Mount is part of chassis body. No idea what for
– Connect speaker wire at radio for easy removal
Mount lip antenna mount
– Get height right (angled to fit in garage and still open hatch)
– Cut screws to height (too tall, hatch wouldn’t close)
Clip UHF connector so that it could be fished
Run antenna coax
– Run along hatch with tape (for now)
– Cut small hole in wire boot and seal with silicon
– Fish coax to wheel well
Steps Continue
Solder PL-259 connector to RG-316 coax
Steps continued
Fabric power cable connections (all with radio in well)
– Anderson power pole
– OEM connector
– Fuses
– Power filter
Shrink tube with adhesive lined shrink tube
Steps continue
Run extension wire under dash
– Zip tie it up
Remove left dash panel
– Pull off carefully from bottom up
