Me too. I see that Edelbrock doesn't recommend hooking it up to the ballast. If it takes 5 amps and never shuts off the ballast only has so much current to operate or if it needs more, the circuit is overloaded. No need to strain our already weak electrical system. A 10 amp delay relay that could be controlled by the ballast wire would be good as long as it shuts off power to the choke in 10 min. or so.
