I to thought that it was going to be hard to install the guages when I frist got mine. your lucky you got all you need in a nice box. I had to peace mine together from what my freind pulled out of the back seat of his truck and what they told me to buy at the auto parts store but I found it all just took me a while.
Back to the install, I wanted to do it right so I took my time and sodered and shrink wraped all the conection. Ran all the wires and zip tied them. All in all it was a farly easy job. The hardest part I think was taking the manifold off driling and taping it. I think I did a pretty good job, even had some girls not belive me the other day when I told them I didnt it my self. I have them mounted on my A piller Boost, EGT and transmission.
If you take your time and read up on what your going to do you will be fine.
