Eh, you'll be alright. The harness work can be done outside of the car... you're connecting the radio harness to the adapter harness. You can sit down at a table and take your time with it, and ask questions here if need be lol. The only thing that has to be connected in the car will be the remote wire, and that will only apply if you are installing separate amplifiers in the vehicle. Does your car have Monsoon? If so, I have no experience with that other than ripping it out... but other members here do.
