Well guys, I went w/a fusible link,,plenty of wire extra for future repairs if needed. GM used nothing before the fusebox, but I thought it would be a good idea(there's 10+ feet from battery to fusebox). I had a nice 40 amp breaker on old black truck, but I cannot find it, & I really couldn't figure a way to mount/wire a Maxi fuse w/o it looking ghetto. The fusible link is easy. Brian
