There are two types (at least from Schroedie). The ones that only blink (usually amber) and the ones that have a steady colour (either white, red, green or blue) en blink amber. The first one has a single connection to the turn signals; the second one has double connections: one to the turn signals and one to steady 12V.

 

Thanks for getting back. Looks like I ordered the wrong model. I'll have to be satisfied with only the blinking.

 

If your Roundels have only 2 wires to connect (+ and -) you can wire them to follow the running lights if you have cbdane's running light kit.
You have to connect both wires to the wires going to the front blinkers, do not connect the (-) wire to ground.
With the running light kit there are two wires that go to the front turn signals (final output of cbdane's connector). If memory serves, both wires are yellow. Turn on the ignition and use a volt meter to determine which lead is the +12v to the light. Connect the (+) lead from your Roundel here, connect the (-) lead to the other wire going to the front Turn signal light. Your Roundel is now effectively wired in parallel to the Front Turn signal light and should work exactly as it does. Obviously you do each side individually. Do not "common" any connections between sides.
