Does anyone have any experience with installing the OEM sonar system into a double cab SR5 Tundra 07 or newer? I'm willing to bet that the factory wiring for this is already in the truck (just like with the fog lamps), and that upgrading to the OEM sonar system is a matter of buying a few additional parts (sonar plugs for the front and rear bumper, display module for the dash and/or factory plug switch to turn it on or off). I'm considering an aftermarket Sonar system, but using the factory wiring (just like the fog lamps) is a big plus. Any direction would be helpful.
