you may want to run it under the car. If you take out your spare tire and everything out you will see 2 rubber plugs. you can just run the wire through that under the car along the gas lines and then up into the engine bay. This is what i did and it is a lot easier oh yeah and there is enough room beside the spare tire so you can replace it with no problem
I ran mine on the drivers side in the grommet that's right behind the carpet near the brake. It's just a little circular grommet. I'd suggest using a hanger and then tying the ring on it and pulling it through. It was really simple! If you lived closer, I'd do it for you.
