exactly as the title says. have the tach adapter hooked up. it says for
4 cylinder 1 pulse clip the brown and blue wire on tach
4 cylinder 2 pulse clip the blue wire only
searched but i coudnt find anything about the 04 ecotec being a 1 pulse or 2 pulse

if it like the 2.2 ohv it is 1 pulse. but not sure
try just holding the wires together and seeing what works.
I would say 2 pulse, since it fires twice every 4-stroke cycle.

fortune cookie say:
better a delay than a disaster.
i have to cut the wires.
so far no one has been able to know for sure. 3 people said 1 pulse and 1 person has said 2 pulse.
kinda feels like the old pull and pray
