Detailed DemonIVR installation instructions please? 1970 duster

And final update, for anyone who faces the same problem as me in the future and finds this thread:

I emailed RedFish and he clarified the install. With the three prong connector removed and looking at the board, it goes ground on the left, red 12v in the middle and yellow 5v on the right. On the left and right connections there are screws available to secure the wires. On the middle (red 12v) connection you can screw a small screw into the socket to secure the wire. RedFish says that this does not damage the socket and you could reinstall a factory or factory style voltage regulator without a problem.

The other tin cylinder with a black wire going to the middle socket is removed and you can install the DemonIVR to the same location with the same screw.
