The 40 amp is between the voltage regulator and the battery. The 20 amps is between the battery and the EHC
I would give Curtis a call out at Wildsteed Works in CA. I believe he was selling and installing the Electronik EHC. I'm sure he could fill in the blanks Bud.It is actually required when installing a Electronik EHC, which I switched over to back in 2017.

That makes sense sir, that's why I was trying to determine a specific location.When I replaced the EHC, rotor/stator, and VR in my '08 mastiff, I used the compufire charging system. 40amp breaker from VR to battery and 20amp breaker from battery to EHC.

Thanks Rottweiler, now that makes sense!The 40 amp is between the voltage regulator and the battery. The 20 amps is between the battery and the EHC
Yes, your correct! I misread the instructions. I'm correcting now.The 40 amp is between the voltage regulator and the battery. The 20 amps is between the battery and the EHC
Good you have figured it out. When I installed my new EHC I deleted the circuit breaker & installed a 40 amp fuse in its place. Make sure when you wire everything up that the VR connection to battery (whether CB or fuse) is to the battery independently. And the 20 amp fuse from the EHC is to the Battery NOT the circuit breaker. Seen here, 3 leads on positive terminal. CB/40a fuse, EHC, lead to starter.Yes, your correct! I misread the instructions. I'm correcting now.
Well to me it’s a case of better safe than sorry. If the VR & the EHC are independently connected to the battery positive terminal it pretty much rules out any possibility of the EHC being damaged in the off chance that the charging system has a issue. It’s like a fail safe for the brain of the bike. Obviously this is just my opinion and you should use your better judgement on the setup. Hope you are up& running soon!Nice install McMorris. Since your using a fuse, I can see why you would need to go directly to battery with EHC fused wire. By putting less connections on the battery, why wouldn't the EHC fused wire not be okay to go to battery side on CB? That's what the instructions call for......??
I agree. That is how I wired mine. You can do it any way you want.Well to me it’s a case of better safe than sorry.

Not an electrician by any means, but it seems like if the EHC fuse wire was hooked to the battery side of the circuit breaker, and something happened to the battery connection of the breaker to the battery, say it got corroded, broke or lost good contact somehow, then everything from the voltage regulator would be sent straight to the EHC fuse and if it didn't blow then the EHC is toast. I could be wrong, but that wouldn't be anything new.Nice install McMorris. Since your using a fuse, I can see why you would need to go directly to battery with EHC fused wire.
