I have a 2004 Toyota Solara SE convertible. Do you have a plug and play wiring kit for it ? I also have a 2003 Mercedes C240 wagon that I would like to put a hitch and Plug and Play wiring. Thank You

We do offer a Tow Ready # 119178KIT that would be compatible with both vehicles, however it isn't a plug an play harness. None of our vendors offer a plug and play wiring option for either of your vehicles.
The installation really isn't too difficult. You would need to access the rear of the taillight assemblies as if you were changing a burned out light bulb. The wiring harness kits include a circuit tester. You'd begin on the driver's side. Ground the tester to the vehicle body, and have a helper activate the left turn signal. Probe the wires leading to the taillight assembly by piercing the wire insulation using the pointed end of the tester. Do this with each wire until you find the one that makes the tester blink along with the turn signal. Attach the yellow wire to this circuit. Do the same for the running lights, attaching the brown wire when the correct circuit is located, as well as connecting the red wire to the wire that lights up the tester when the brake pedal is pressed. Ground the white wire to the vehicle, and proceed to the passenger side where you'll attach the green wire to the circuit for the right turn signal.
I'll link you to an isnatll video showing the harness being installed on a 2007 Toyota Avalon. The install procedure would be different on your vehicles, but the procedure shown for using the tester to find which wires carry which signals should be helpful to you.
For a hitch for your C240 Wagon, I'd recommend the Curt Class I hitch, part # C11824. I've linked you to the installation instructions. You'll also need the # C45521 ball mount and a 1-7/8 hitch ball # A-80 or a 2 inch ball # A-82 and a hitch pin, part # PC2 to complete your towing set up.
