Your replacing the whole harness so this might not be relative. If you are doing any repair, try here:
http://www.wirebarn.com/I ordered a variety of short lengths. Spot on for color, proper under hood insulation temp rating.
I believe Lectric Limited will custom build a harness to your specs. It was a toss up for me between the two mentioned. Once I got the harnesses of the shelf they were in far better shape then I remembered, and not hacked. Shy a few pigtails needing replaced. So I went the route of restoring them. Did not take long on Ebay to find the few connector sockets I needed. Relatively cheap and spot on match. Even scored a used blower motor lead for a few bucks.
Also, I have read in various posts about the " white clothed resistor wire" for the ignition. I doubt here, but I have read threads on other sites stating the existence negates the need of a ballast resistor. Mine read 0 ohms. Interesting enough, following the wire down a few inches into the harness, it loops. At this loop is a non-insulated area with a piece of what looks like shrink tube (loose) insulating it.
Anyway, if your running points, you need resistance in the circuit, I believe operation at 8v. Electronic, no resistance needed.
