First I started off by cleaning the basement a bit, since I need all the floor space to lay out the factory Fiero harness, one thing that I found is that the Fiero harness has a lot of lines that cross over each other in the dash area, for example the power window buttons run on a separate line from the main line that runs from the fusebox to the engine bay, I hope to clean that up a bit when I modify the ION harness.
After laying out the Fiero harness I started working on the ION harness, I thought about just laying the ION harness on top of the Fiero one, then cutting and hacking to the different lengths, but I realized that won't work too well with all the wire protection tape/loom in the way, so I started off by hanging the ION harness from the ceiling and removing all the wire protection off the harness. In this way I can start off the modification by locating the main interior fuse panel in the desired location on the Fiero harness, then connector by connector and wire by wire tracing the exact route that the harness is going to follow ending up at the proper location in the Fiero harness where I can trim or lengthen the wires to suit and use either the Fiero or ION factory connector to the desired part.
This process is probably going to take a few weeks in the evenings/weekend, but it should end up with a nice clean harness that "should" line up nicely in the new car.
