I decided to add in-line outlets to the existing TV power cord. That is what this Instructable describes.
NO, the intro photo does not show what we have in our house, but it does make a point.
Step 1: Buy the end-of-line outlet type connector.
There are many of these, meant to just clip over the end of a standard 18 gauge double strand cord. You lay the cord into a groove in the outlet, then clamp the connector closed; there are prongs that penetrate the cords to make the connections.
I bought one, thinking I could modify it to meet my needs.
