Hey guys
I have been playing around trying to find a electrical fault in my premium loom and have noticed the earths of the coils are actually wired back to the sensor earth (black/white cable) ?
Car has been running fine up until now but im just checking if you think this might be effecting the earths somehow? Or should it change it over to a chassis earth?
Secondly while iv got all the wiring out i want to be able to manually switch the rotational idle one and off as needed. What is the easiest way to do this?

Never wire coil earths to the ECU. They go the cylinder head as the return path for the spark energy.
