Well I am being serious, I think they could be a lot better, I don't use msd products so can't comment on their instructions. I just think from experience it's so much easier to pick up the trigger wire at the rear by using the old pump feed, this wire is only a trigger so as long as there's continuity it will be fine. Lets be honest all the the new loom relay etc can be neatly installed in the spare wheel well, out the way, plus I normally mount the new relay to the fuel cut off housing which gives quick acces to retaining the cut off switch.
