Found this here on JG:
Don't take off the passenger side tire. After prying off the felt/fender liner - I looked around for at least thirty minutes for the infamous orange plug....nothing.
Do go from the top. I'm no body builder, but I squeezed my arms down the backside of the engine compartment (literally against the firewall to the cabin of the vehicle) on the passenger side and then reached forward until I felt a very malleable rubber. Pull, and you have just found the infamous orange plug. I then ran the cord straight down v. going through the back part of the engine compartment.
I had trouble getting the leverage needed to push the plug in with my left arm, so I took the engine cover off and put down several thick blankets, laid across the engine, and put my right arm down the back of the engine compartment - success. Zip tie and then figure out what you are going to do for an extension, b/c unless you want to leave it flopping around from under the hood, you'll need one.
I don't have any pictures, because I literally never saw what I was working with. I do recommend a long sleeve shirt if you like skin on your forearms.
