Auxiliary Power System Under the Hood

I spent more time today working on my auxiliary power system install. The more I get into this, the more complex I realize it is. Pictured here are the components that are going under the hood. My system is designed to use a solar panel to charge the auxiliary battery when the FJ is parked. The solar panel is mounted on the roof rack. Shown here is the charge controller:


I also have a relay block for 4 relays. Each lighting system needs a relay and this consolidates them into one bank. Pictured here is the back side of the relay block wired and ready for install:

The under hood components are mounted on a panel that is mounted to the battery clamp. The panel has the, fuse box, relay block, solenoid, and charge controller mounted on it:

I hope to finish tomorrow.
