Somehow, CC does the switching with the control box that provides the pulse function, and the existing switch was not compatible with the new setup.
I ordered a 15A, DPDT, OFF-ON-ON switch from Mouser Electronics, that is made by Carling Technologies. The issue is that in position 2, a single blade is powered, and in position 3, both blades are powered. Because the new lights have their own built in wig-wag circuit, you need to have position 2 power the lights, and position 3 power the wig-wags, as anytime both sides are powered the wig-wag will take priority.
That makes the labeling on the main panel reversed, which required the new panel with ON in the middle, and PULSE on the top. Carling Technologies did have a DPDT switch that only powered a single blade in either position 2 or 3, but when it arrived I realized it was too wide to fit into the existing spot.
Once again, Jim at Engravings Unlimited knocked that out for me. Since most flying is done during the day, with pulse selected, that makes it easier to just turn the landing light switch all the way up, matching all of the other switch positions.
I did tap off of the main bus to power the new circuit.
