I certainly understand not wanting to mess with wiring if you don't have any experience with it. There are some wiring harnesses out there that make it really simple if you wanted to give it a try. The Raxiom Wiring Harness is one option, but there are others!What is the place called? Do you have their number and do you know how much they charge?
With a harness like that you're just connecting color to color and hooking to the battery. Just another option for you! Let me know if you haven any questions.
