I am planning to change over to a 12 volt system and I need to replace most of the original wires. I was looking at the wiring harnesses available through classic industries. Their tech guy was suggesting to use the modern upgrade harness because of the improved fuse box but I keep thinking that i don't need a modern style(19 circuit) fuse box for this truck since I am not going to a v-8, no ac involved or any of the other circuits, not to mention the additional $200 cost. I was looking for suggestions about what would make the original style wiring better as far as adding a few fuses for safety? | | | | | Joined: Aug 2011 Posts: 149 Wrench Fetcher | | Wrench Fetcher Joined: Aug 2011 Posts: 149 | check out speedway motors.they have 12 wire harness with labeled wires,12 fuses.i belive i paid 139.00... | | | | | Joined: May 2005 Posts: 8,983 Sir Searchalot | | Sir Searchalot Joined: May 2005 Posts: 8,983 | If I understand what you want to do:"add some fuses for safety": Add some $4 inline fuses, fused to the amp draw of the components you wish to "add" safety to.. If your wiring is good.
VERY IMPORTANT: Read the various opinions/instructions on this forum for switching to 12V. Some components will do fine without replacement, some will not.
See O'Reilly's: replacement parts/lighting and electrical/fuse and fuse accessories. All kinds of ideas there.
If you are "restoring", do it with all new wiring and fuse box, etc. If you are wanting to get it going and drive without much bother/money, change bulbs and such items that will not run on 12V.

Plenty out there to choose from but you might as well get a new fuse block with modern fuses and enough circuits to do what you need, plus maybe a few extras.
My fave are the new fuses that have a small LED that lights when it blows, makes it a no brainier to find the problem.

But as pointed out, any more demanding upgrades requires a better fuse panel.
