This is the full complete unit and the full labeled harness with a 2.5 bar map sensor. It was uesed for dyno testing my brothers 68 f100 pickup truck with a 383 and twin t63s. He wanted to upgrade to the 3.57 so he sold me the 2.2 and I had to buy the harness new. The harness has never been used. Now that there's a MS PnP for my Hayabusa I dont need this box. Asking $ 250 for both and I have 2 palm pilots with a harness that I will throw in. call me at 904 703 9015
