[Mgs] New Wiring Harness

[Douglas Gaither]

I was considering an entire new harness because I have the blessing  
from my wifey to do so.  I do realize this is a rather involved  
undertaking and so I would still consider either repairing the damage  
or replacing the rear harness.

Either way, I like the idea of fusing the rear part of the harness,  
what size fuse would I use?  Would you suggest just an inline fuse?
