I should probably have mentioned as well that the coils were all tested and fire properly. Havent confirmed if they fire properly in order, but they all develop a VERY healthy spark in each spark plug, and via a spark plug gap tester. Coils are on plug in valley of head, with stock rubber boot. I installed a spring to help keep the coil connected to top of the spark plug. Coils all have 12v, two earths and proper 5v signal wire.
