Here is the schematic sheet I'm using. I think I can actually just reuse my wires and leads without connecting any new ones. I really just needed the female plug, although of course you can't get that for just $4, you need the whole $30 kit.... The amazon picture looks like you just use 6 cables, and I see I only have 6 free cables. I probably will end up just cutting off the terminals on the current wires, and soldering an inch or two of the new wires + terminals onto the ends.
This picture is from Amazon, unfortunately he does not show the back end of the plug.
However I can't tell which colors exactly are running into each of the inlets. According to my schematics, I should have dark green, brown, orange, light blue, tan, and yellow.
The 6 wires I have are dark green, brown, orange, light blue, tan, and yellow, so far so good
However my schematic calls for something different, unless I'm looking at the wrong schematic. It says it should be for 95 and up trucks, and it's from the Haynes manual. Maybe someone can take that Amazon picture, and use MS Paint or something to tell me exactly which color should line up with which inlet?
