My 85 was a hacked up mess when I got it, worst wiring butchery I've ever seen. I'm talking bout the main hot wire from the alternator changing color and gauge size 3 times and b the length of the slant 6 valve cover. And crudely twisted and taped at each junction not even wire nuts to join them (I hate those but they would have been an improvement)
I ended up getting a replacement harness from a junkyard and went thru it with a fine tooth comb before I plugged it in.
While there I deleted every damn fusible link that was there. Don't scream, everything is fused. I went back to the yard and looked around at newer vehicles with under hood fuse boxes, I decided on one from an 89-92 ranger with **** fuses. I subbed everything that used to be fusible linked to a maxifuse.
I did some research on this before I did this and found a tech bulletin from Littelfuse on the creation of the Maxifuse which actually was developed to replace the fusible links. I emailed littelfuse back n forth while I was at it.
I never thought adding sifter wire 3 gauge sizes smaller than the parent wiring in a circuit was a good idea....
