Bought Bosch coils (red) and spacers (red) from intergrated engineering (not sure about the function of the spacer; only side slots of coils reach into them).

Also got the ECS harness. Plugs for coils fit, what what are those 2 wire looms with loose pins for? where are they going?

I thought I need to cut off the ECU to ICM 5 pin connector and hard wire to ECS harness. Not so?

Need some help.
