1967 Dart repro engine wiring harness question

I bought mine from Year One and yes, it's made by M&H. It was on back order at the time, but once I placed my order, they built it and had it two me in a few weeks. Seems to be a pretty nice piece although I haven't gotten to that stage of my project yet. I would contact M&H directly and tell them EXACTLY what you plan on running under the hood and see if they could build you one with the accessories you plan on using.
