You can buy little fuse blocks, have a post on the end that the power or ground comes in on. I think powertech or something makes them, they can be fused, use the appropriate amp fuse i think 25 is the max per fuse & don't forget to allow for voltage drop in the wire gauge size. You can get them from jaycar, rtm ect. Start around $20 each, just put them in a friends ski boat last week.

Hi

      Running fans ignishion and other accessoreys from 1 wire may not be a good thing, Too much load for the  ignishion wire. Even worse if you are planing to use the resister wire that feeds the factory coil.

         I added a fused relay box to my car with seperate relays/fuses for the extra stuff (like in most later model cars), Fusabel link and heavey feed from the battery to the relay box and seperately fused outputs that are built in to the relay box. Trigger the relays from the origonal wiaring loom and the relays take the load. Reduces the load on the old switches and is a lot safer than overloading the exhisting system. I ordered the relay box on ebay and it came with relays and crimps to wire it up as needed.

 

   If you do not want to go that far atleast relay switch the high load stuff so you do not overload the factory system.
