Now includes six stainless 90 degree adapters which go between the coils and wires. You won't see any wires looping down from the bottom of the coil - they point straight towards the ICM.
Wire color is based on availability.
Here's a little bit of information about the wire I use:
Waytek Wire’s cross-link automotive wire is constructed with chemically altered polyethylene insulation, making it more durable and resistant to heat than standard GPT automotive wire. Our auto wiring features a smooth surface finish and is resistant to moisture, grease, oil, gasoline, most acids and solvents. It’s typically used in high temperature areas, such as connecting wiring to circuit protection devices or fuse blocks in engine compartments or automotive wiring connectors. Our cross-link wire meets SAE J1128 standards and is designed for applications where higher heat resistance is required.
