the trunk harness has a cloth type of wrapping, doesn't it? Not sure where you can get any of that. The wiring harness sold by Year One (made by M&H) is very good. Correct wiring, sockets and wrapping.
the original trunk wrapping is a cotton weave if I recall. I believe M & H can re-wrap your original harness if you call them directly.
The M&H repro harnesses are good reproductions, however the sockets are not 100% correct for OE. The side marker and two of the four tail lamp sockets differ from originals in appearance by quite a bit.

was this ground wire on all cudas??? i have an early build 1970 and i restored the original wiring harness and never saw any wires routed to grounding the harness. no cuts or anything. very interesting info......
The pics above came from a survivor '70 Cuda I owned that had an SPD of November 5th '69 and was built at the B-Hamtramck plant.

Ditto, the cuda I just finished had no signs of this ground wire( hamtrack built car btw)
I will say. The one I did, did not have these style nuts holding the lamp in

I am pretty certain your Cuda would have had the additional ground strap. There will be no indication on your regular harness as this strap is entirely independent.
You could always just wire it up without the ground and see if the left side works (if in doubt)?
Everything works fine without the ground strap. thought all the lights were grounded to the the housings. when you pull a light socket out with lights on , the pulled light goes out.

I just removed my taillights from my 70 gran coupe and it has the same exact ground wire. My lights have never been removed and the car is a 9/69 build date. Although my mounting nuts for the lights look just like the acorn style nuts holding the small side marker light in on the above photo. The photo Bill linked for the retaining nuts looks more correct for a challenger. 
I have also owned a couple of '70 'Cudas with that acorn style as well.

I wonder when the change-over occured...My 70 {SPD 9/11/69} had the acorn style...The above engineering drawing shows them being used...
