Changed out the electric antenna today for the Tacoma Whip setup. There are plenty of instructions around the web detailing this but I'll still share some pictures.
Here is the part number from the standard fixed antenna base:
Here is the black tacoma whip antenna:
Thought it cool the antenna came with a little wrench to keep in the glove box:
To get to antenna base, you have to remove part of the inner fender well. I found this very difficult even following the instructions I found on the web. I think the biggest difference was the person that put up instructions and pictures didn't look to have limited fenders and mine does. What I found is on the back of the limited fenders there are clips holding the liner. Also, there are a few bolts to remove. Here are some pictures.
This is the power wire coming pretty high up in the fender above the coax entry point and above the tire. This is where the motorized antenna connects for power. After disconnecting this harness plug, I just wire tied it to the hose so it wouldn't rattle.
Coax entry point. Comes out just inside the passenger foot well kick panel. The rubber grommet came with the new antenna base.
New antenna base. This mounts to the same spot as the electric motorized antenna base. Basically one screw holds the bottom and the top is sandwiched through the sheet metal body.
And all installed. Has a little lean, and I'm not sure if that is normal or if I somehow have the top off center, but actually I kind of like it as it keeps the antenna a little more inside the path of the truck if that makes sense.
