Don't pay attention to the numbers written on the blue tape according to what slot they are in on the 4 way clip. Although they are correct for firing order on the opti, they didn't finalize in the clip this nice pictured way when I put the opti boots on the opti. 2 were crossed looking. These blue tape numbers winding up in the wrong clip slots is because I assumed the wires went up hill in the slots like the engine goes back from 1. ie 1,3,5,7. I had 1,3,5,7 within post 57, instructing (previous post before editing) to place numbers in slots going uphill in the 4 way clip in the order of the cylinders from the front of the car to the back. In other words,, on the opti going up its 1,7,3,5. not 1,3,5,7 like the engine going back.. They are not the same. Anyway, place 1,7,3,5 in the clip from bottom slot upward.. Then snap shut the clip for nice arrangement. My mistake. just clarifying for anyone that wants to focus on the tape numbers to clip and end wondering why they have a crossed looking placement compared to mine in my next photos. it's because I unclipped the wires after the pic was taken and rearranged them before taking the finished picture in the next post.
