Engine harness is junk

I started inspecting my harness before reinstalling it into my 71 Scamp and so much of it is complete junk. The main plug at the fire wall is melted at the fuseable link wire and a lot of the wiring is cracked with bare spots all over..

I planned on rewiring it next year after I got some more money but I just need to get the car back running again.

I dont have any new connectors and I doubt I can find the correct wiring terminals nor do I have the time.. So I've eyed up the harness Classic sells. I have electronic ignition but the only one they list is this one.

Its listed for a 340 with electronic ignition.. Of course the description is vague but a lot of the wiring and connectors match mine. Has anyone ever gone this route? What other options do you guys have?
