Since these cables are pretty short and are around the back side of the TV, I cut off the connector and spliced in a new 4 conductor cable about 8 feet long so I would have easy access to the wires from my work-bench. At this time you could drill a hole in the back of the TV cabinet and poke the wires through so you can put the back cover back on, but I left mine off in case I felt the need for a good high voltage wake-me-up shock later in the night.

First out you need to remove the back cover from the TV to expose all its guts. You prolly want to unplug the thing before you take the cover off to avoid being shocked too badly. And don't be sticking yer fingers all over the place in there either, some of the components in there can hold a charge of several thousand volts for hours. Next locate the horizontal and vertical deflection yolk coils attached to the CRT. These are going to be coils of copper magnet wire wrapped around the skinny part of the picture tube. Trace these two coils (four wires) to their end, usually a connector plugged into the main board. Yank out the connector from the board, mine looked like this:
