I was more concerned about the extra load on the alternator causing charging problems, but thanks for the info! Once I get my rebuild finished, I may either contact you for a kit, or build my own (i'd like to try to house as much of the system as possible inside the relay box to keep the engine bay looking stock-ish)
Edit - Just noticed that your prototype actually seems to mount inside the relay box. My mistake.
