Basically wiring a car from scratch for the chassis(ie. non engine) circuits.
And am contemplating this:
I have 6 switches, 1 will be starter engage, 1 will be accessories(generator and other will be on this circuit) (ignition, ignition coils and ECM will be on this circuit), fuel pump, fan, headlights(retaining factory Hi/Lo switch, which appears to power them in either mode, so I will run switched power through to the Hi/Lo switch) And parking light switch.

My question is, should I route all my accessories that I am putting on switches through the accessory switch, ie. run power to acc. switch, then run pwr from acc switch to headlight switch, and park light switch. Or should I just junction block the power near the switch panel, and branch off individually for each switched item. My first time wiring something up from scratch and just not sure which way is more logical.

Re: Should I do redundant switches for my accessories, or run power individually for

Nm, decided it would be best to do a junction block, less risk of drawing too much current through one circuit, and don't lose everything if one circuit grounds out and trips a breaker.
Anyone know a good place to get an insulated junction block for batt +? I looked into it once before and most seemed like they were meant for grounds.
