Depending on the vendor, you acquire a harness that meets or exceeds OEM specs for insulation color, insulation type, wire gauge, length, branch dimensions, and for the most part, termination. Of course, even 'complete' replacement wiring harnesses require minor tailoring.
IMHO - If you were to retail source
all of the materials (SXL/PVC/GPT wire in the appropriate colors and gauges, plus the many varied terminals and connectors) needed to fabricate a complete new OEM style harness, you likely would have between one-half and two-thirds the cost of a new pre-fab harness. On top of that, add your time and frustration to string and accurately dimension the harness with branches at the appropriate spots. It's one thing to repair/replace a section of existing harness, quite another to build a new harness from scratch. Even with a dimensionally correct original harness to copy, building a harness is tedious. So, you have to ask yourself whether the $200-$300 in initial savings is worth more to you than your time.
