Dragstar has a wiring diagram that is provided with every dragster that they do the wiring on. I had some additions I wanted and they accommodated my requests and added them to the diagram. Every wire is color-coded and easily traceable. The one thing you might notice we're is missing is a fuse panel. We talked about this at length and we agreed that there are a few things we wanted protected and some items just don't need one. Here is what we decided and everyone has to make his or her own choices.

Items we put fuses on: Delay Box Power supply (15 amp) and Transbrake solenoid wire (20 amp)

Items we use fusible-links on: Fuel pump power supply (40 amp) and Water pump power supply (30 amp)

Some racers have every circuit fused. I cannot disagree with this practice and it might be a great idea in some situations. I have a master disconnect located next to my left hand so, if I feel there is an electrical problem, I can shut down all power immediately. I also am sure I don't want my fuel pump to blow a fuse just as I pull out for the final round because the pump is hotter than normal, same for the water pump. If a blown fuse could cost me a race I'd rather not have a fuse in that circuit. I would choose a fusible-link wherever possible. That way you can get by with a brief overload situation and possibly save the race versus having to give up a race to replace the fuse.

Every situation is different and everyone has a different opinion. On this car, where every wire is new and properly prepared, I am not as concerned about a short-circuit as I was in my Dart that had a lot more wiring and had been re-wired several times over the years.
