A few weeks back I posted this photo...
These were 3 x 6 AWG runs from my 2nd battery to my roof rack via the inside of my snorkel. 2 were +ve and 1 was -Ve. My logic for only 1 -ve was that one of the +ve's was for my KC spots and the other was for perimeter lights neither of which would be on at the same time. Whilst I sure that never happened, the above damage to the -VE cable was the result.
With the lockdown, and all my planned maintenance already completed in the cooler winter months, I decided to re-think the wiring for every electrical circuit I have added since I owned the truck.
I ordered new cable, built wiring diagrams, measured everything and completely built my own harness for all my interior electronics. I also decided to tidy up the engine bay and remove as much of the single use wires as possible.
To replace the cables to the roof rack I had to remove the snorkel which led me to remove the fender. When the fender was off I realised there is a siht load of room in there. I know that Toyota already mount relays inside this space so I thought I would take it a stage further.
On the passenger side I fitted a fuse box and a connection box plus my ACR and a relay or 2.
On the drivers side I have just fitted a few relays which power up the front spots, Aux fan and my rock lights.
End result is a tidy second battery and engine bay.
All the open connections are protected by heavy insulation just in case someone was to hit me side on. Quite happy with how this turned out..
