The Duster I now have has a Painless switch panel and relay/fuse bank that rivals a small Cessna..... I hate it, and WILL get things changed or at least straightened out if I choose to have an "off season". Stuff I have: waterpump, fan, electric gauges (want them switched separately so I don't have to have the ign switch on), racepak and O2 sensor (been advised to wire that up separate due to the amp draw... basically switch it on in the lanes to heat it up), trans brake, line lock, shift timer, fuel pump. A lot of the accessories can share a switch, but there are some I want separate. I also have the tach into the same switch as the t brake circuit... that lets me know that it's powered up for sure. I'll sit down and map all the stuff out one day....
