I am doing a ls3 418 stroker that I'm putting in my 99 TA. I have the holley valve covers and realized my old coils will not fit. So I bought a complete set of ls3 coils with the harness and brackets. I want to make sure I am putting them in the right order. Does anyone know the color codes for the ls3 coils so the will be in the right order? I appreciate any positive help! Thanks in advance!
The most often mistake is the outer terminals, as they are opposite, though your new coil connector is of a different size, NOT your case.
You may want to report the coil dwell amount as that too is different.
My guess is that you have fitted a GEN-IV coil.
There is NO RH/LH Sub-Harness difference.
I work with Doug Flynn, do you have the latest Firmware ?
This day we ALL celebrate the Mass of Christ, most know this term as Christmas.
He was the God who won the "battle", here on earth and elsewhere ? , proving he ruled the mass of the universe (10*55 in grams), in my eyes.
Then he stated mankind was created "in his own" image.
The concept could be that "simple".
Would others here agree ?
Lance, BTW I will shurely get some "heat" on this observation !
Thanks but I also do not know front to back on these new coil assemblies. I assume that will make a difference. They are for 2007-2014 Chevy Suburban with a 5.3L. I attached a picture of the new coils if that helps.
