Hi Richard,
I fitted the holder with a 30A fusible link. The holder is to the left of the Starter relay/solenoid.
It provides overall protection for most of the cars electrics (and that cable look that runs under the dash!

I will add photos of the additional fuse box - Morgans (like most cars built back then) were not good at protecting the electrics...
