I have ls7 style coils and harness going on my lt1 with the ltcc. From all the info I can find it looks like I have two drivers side sets as the wiring is purple and light blue and green and I think red or brown.(these are the colors that are different) ok so im mildly concerned I get it in correct firing order and it runs one way and doesnt the other. If I have purple on 1 and 8 it runs(purple is supposed to be on 1 according to info I find) then light blue 3 and 6 and so on. This is the way it runs and seems to run fine but only started it and let it run for less than a minute. Im getting the rest of my parts put back on and hopefully someone can confirm im ok like this(im assuming I am as it would be just like taking drivers side coil harness and putting it to passenger side(plus with open headers it seems to run good) thanks and I will also post in the ls tech
