I have just one concern and this may not even be an issue depending on how the wiring was done? Are all the 30 amp lines that run back to the cabin/latching relay protected by the fusible link?
I wasn't sure where you cut the lines going to the fusible link -- before or after the fuse link battery feed connection? After would be fine - so that if one of the new wire lines accidently shorted to ground -- the link would blow. I think this is what you did -- but wanted to double check?
