If you ordered a base Tacoma model, chances are you are wired for most aftermarket items.
This makes it easy to add things like a backup camera, mirror turn signals and more.
My Tacoma (2nd gen, 2014) thankfully was pre-wired for a backup camera. To check, I looked under the bumper near the gap between the truck itself and the tailgate.
The tailgate inside cover comes off easy enough with a hex bit.
What I found was a blank (dummy) camera module.
I bought my camera on eBay, it’s been working ever since.
Unbolt the two bolts holding the module in
Make sure the harness underneath the bumper leading into the tailgate is plugged in, and automatically your stock dash will detect the camera.
