Hello, Simon and welcome to the forum. I'm sure you will be able to receive a lot of useful advice from the fellow members
As regards your specific query I remember at least one contributor who has fitted an ELS to their Myford lathe, so hopefully they will be along soon to give you some guidance. In the meantime, I have fitted an ELS, and specifically one using James Cough's proprietry parts to my lathe , which is very similar in size to the Myford ML7, although it was manufactured a little further east of Beeston. There is a brief description of the process in my album here:
Fitting an ELS to my lathe
And a rather more comprehensive series of videos on YouTube, here
It was reasonably straight forward to do, though I did have some awkwardness with some of the wiring. Someone with your background should breeze through that, I would think.
Anyway good luck with the project, you will find it an invaluable addition to your lathe, as I certainly have. Beats changing gear sets hands down, both for metric and Imperial threads as well as the ability to alter feed rates on-the-fly and producing left- or right-hand threads at the push of a button.
