Hi, I read your post last week, went to the Hooker site and downloaded the install sheet and read it to see what differences from the Doug's and TTI'S I've been installing. The instructions and diagrams were so good, I didn't respond to your question because I honestly didn't think I could do any better than the info provided by Hooker, and was hoping someone else might add something. Perhaps others feel the same, pretty basic. Good luck, cheers
