Is just right like John detailed and is a GREAT useage for the relay, which usually we use it on the other way around. But my main concern is if the low voltage coming out from ballast ( the same that feeds the coil on RUN ) could still activate the 86 prong to keep closed the circuit allways to 87 side ( ign 2 circuit ) which will keep on low voltage rate while in RUN. That's why I think could be a great idea to get a diode to block the low voltage coming out from ballast up to ign 2 side, just right before the splice to feed the 86 prong.
