Hit the junkyard. Look under the hoods of newer vehicles, I've pirated a few for my uses.
I like the ones under the hood of 89-92 rangers.
I used one to delete all my fusible links on my 85 D150 by running everything that used to have a fusible link in it thru the fuse box instead.
We did the same on my son's ramcharger when we deleted the TBI and went 4bbl, that one came from a 98 zx2.(escort)
