1964 Tbird, Rostra cuise control questions

[ak7an]

I plan on installing a Rostra cruise control on my 64. I was hoping that someone on here would have some knowledge of the normally open switch that Rostra sells with their kit. Here is a pic from their install instructions showing that the "ON" switch when closed is not connected to anything and I am sure that is just done out of convenience for the drawing..
This has to be wired to a resistance to ground and I need to know how much resistance to ground their is.. If anyone knows plz let me know. The reason I am asking is I already have a set of normally open switches installed and would like to utilize these..
Thanks
