Is the thermal grease applied between the ICM black plastic component and cast iron/heat sink? OR, directly to fender - between fender and ICM?
Where do I apply the grease????

Apply the heat sink compound to the device you're mounting on to the car body. Apply a thin, eve, coat. More is NOT better, it is worse as it will not conduct heat so well.
In reply to someone else, the EZL in the 300-24s does not need to be insulated from the car body, it is at ground voltage. It is not like the old power transistors that were at collector voltage and needed to be insulated with mica washers.
Over in the UK we started a thread about repairing these things. We believe the most common failure mode is the output devices but we don't know whether the unit can be invaded and repaired. Does anyone here know?
Does anyone have a broken EZL that they could give to an electronics wizard for appraisal?
Best to all.
