So I finally have all the parts to rebuild my axillary electrical system for the FJ Cruiser. I was using Blue Sea fuse boxes but I have found a much better box for Automotive applications. The system is being designed to run off an axillary battery system with both switched and unswitched applications. I will have a fuse box under the hood, 1 in the passenger compartment and one at the rear off the FJ.

Here is my list of systems that the auxiliary power system will control:

Under the hood:

Switched

1. Winch Control
2. Fog Lights
3. Rock Lights
4. Spot Lights / Off-Road lights
5. Rear Fog Lights
6. Inside Front Fuse Box
7. Inside Rear Fuse Box

Unswitched

1. Inside Front Fuse Box
2. Inside Rear Fuse Box
3. Master Power Solenoid
4. Under hood Accessory Plug (Used for work light)

Inside Front Fuse Box

Switched

1. Flash Light
2. CB Radio
3. Computer / GPS
4. Fog Light Switch
5. Backup light switch
6. Rock lights switch
7. Spot Lights switch
8. Rear Fog Lights

Unswitched

1. Accessory Plug
2. Map Lights

Inside Rear Fuse Box

1. Ham Radio
2. APRS Radio
3. TNC

2. Accessory Plugs
