Intercept pin headers, three way or the header?
You can make your own if you just want a few.

Take some Right Angle headers and solder them to the straight header of the other gender.

Tape them onto the workbench to align them as best you can and solder the two ends first.  Then solder the rest.  You will have pins sticking out the side.

If you want to have longer pins look for wire wrap sockets and headers.

If you need a DIL header with break out you will have to use two SIL RA headers soldered to the DIL header so that the break out pins stick out to either side.

If you just need a couple of signals I would use a header with longer pins and just solder your wires to the pin root. If you have easy access to wire wrap wire and tool you could just connect wire to the long post/pin and use it to make your connections.  However remember that wire wrap wire is solid conductor so has a finite number of bends before it breaks.  I find that too often the number is N-1 available bends where N bends are required to complete the assembly task.
