I used a 7 circuit painless wiring setup. worked good. Word of caution, think about what you want KEYED & HOT. the setup I got had too many "always hot" circuits, I dont like this as it can put a draw on the system if I have short or some kind of issue aka my tach was wired to HOT always and it put a draw on my battery and killed it in 2 weeks, i tracked it down and moved it to keyed on circuit and never had any issues. the painless wiring is pretty simple to hook up.
