I had an HI-6, and IIRC, thw wiring was way similar to msd 6al, so there should be some diagram sources on internet somewhere....



What is wrong with this diagram.

I have never had a problem timing mine and use a dial back light and set total timing. I have not noticed a bit of difference in run quality or performance gain over my home recurved Mopar set up with a chrome box. IMO it was a bunch of money spent needlessly. Only thing that I gained was a rev limiter.
