I think between you and Don Shockley I at least have a plan now for the circuits I'd like to add. I don't have a AJB in the back I'll be going straight from the Battery, switched by a relay in the manner you described above, then on to a home made distribution setup. Do you remember which unused fuse sockets you found and which you used? I've looked at F37 (PAM) as its an option I don't have. If you have photos that would be greatly appreciated.
