I have the heater and wipers hooked up to the ignition switch for now. I wouldn't think the ignition switch is rated for both of them so I would like to create an accessory fuse block for both of them (and maybe a radio if I ever hook it up).
I wired up my dome light last night. I found that the headlight switch has a connector for the dome light. I'll probably put an inline fuse in that line or move it to an accessory fuse block when I set it up.
For you guys that installed a accessory fuse block, did you run a new hot feed off the battery, or after ignition switch, or off headlight switch?
