NSS harness carnage!

After being fed up with the random no crank/no start issue with the Duster and never knowing when I'll need to jump the relay with a screwdriver I finally pulled the whole NSS harness out and dissected yrs of electrical tape down to bare wires. I've already replaced the starter relay, ign switch, nss, starter etc while doing other things so the harness itself was basically the last piece of the puzzle un-attended too. This carnage is what I found. Multiple splices in multiple location with crappy crimp connector from over the years of patching. So I cut it out close to the bulkhead connector, spliced the wires together to bypass the switch just to test if it would crank...fired right up no problemo! Needless to say I'd fail tech at the track without a functional NSS, and I dont want to drive it without one anyway. So a new harness is needed...bad. Ordered one from Classic Industries...but it's for a 72-74 B/E body auto...they dont have one for an 70, auto A body! Only 69 A body, manual trans! Then a bunch for various years of B/E bodies both manual or auto! After looking at the pics, the one I ordered looks the exact same as the one I pulled off on both ends....so hoping they are pretty much the same! If not anyone know where you can get a new harness and not just the connector with pigtails to splice in? I cant seem to find an exact replacement full harness anywhere...
