ignition coil on ka24e

[180weaver]

I bought a coil from nology and am now realizing that the plugs from stock are a bit different. It has two plugs, one light green w/ a black stripe and black with a red stripe. Anyone know exactly which one is power and what the other one is for. The new coil only has a pos and neg connection. There is also another individual ground, but I am not positive that it is for the coil since there is another small unit below. Any hellp is awesomeThanks

red is always positive

green indicates neg side of the coil

black is a chassis ground
