There's more than plenty of room to safely run the 12 gauge wires from the blade fuse holders out from under the back edge of the relay panel closest to the windsheild.

I didn't know there were 2 phillips head screws and a plastic standoff spacer under the one closest to the windsheild. They must have been dropped and lost before I got the car.

The location of this wiring mod as well as the drilling and holes were specifically located where they were so that the state of the fuses could been seen by me without removing the cover and also so that the next owner or any mechanic working on the car (if there ever is one) would clearly see this mod had been done. These are the two fuses you quickly want to be able to see on a dark and stormy night as you poke under the hood in the middle of the mountains.

If I was working for NASA or Boeing, I would have put in grommets but really ... I am a SHADETREE mechanic ... we don't need no stinking grommets. (Edit) Truth is ... I subsequently used some 1/4 hose and made grommets/sleeves for the wires ... risk mitigated. [/B]

Purpose is to take some load off the original equipment single wire/two relay design which was prone to blowing fuses due to overheating.

I am no electrical guru so don't know if relays are constantly powered. Someone much smarter about electrical will have to answer that question. This was just my interpretation of someone else's modification that I picked up from this excellent fuel pump wiring thread ...
