This page is primarily notes for myself so I can keep track of what I've been thinking with the wiring for the Land Rover. But others may have useful insights or just be interested, so I'll leave this here publicly available.

I've got to remove the firewall/bulkhead from the car to patch the holes in the footwells. Doing this will require most of the wiring to be disconnected so I figure it'd be a good time to put new wiring in for everything that will need it and replace the existing wiring that has been a bit hacked up and generally worn out by previous owners. With that in mind I need a list of things that need to be wired up and this is it below:



Sink Current (A)

Source current (A)

Headlights High&Low    
 Park Lights    
 Rear Work Light    
 SLA Battery    
 Battery Isolator    


 Hazard Lights    
Dash Lights    


  • Tacho
  • EGT
  • Ammeter
  • Manifold Vac
  • Voltmeter
  • Oil Pressure
  • Fuel tank level


  • Switch
  • Coil
  • Plugs
  • Dizzy
House Bank Charge    
Air Compressor    
Windscreen Wipers    
Windscreen Washer    
Starter Motor    
Electrc Fan    
Heated Windscreen    
Heater Fan    
 Driving Lights    

 Trailer Socket:

  • Indicators
  • Brakes
  • Reverse (?)
  • Park
 Trailer Brakes    


Ok, that is a pretty big list, particularly for what is supposed to be a simple car. But that list does have in it many things that I am planning to do, or want to leave open the ability to do later If I choose to go down that path. Anything that isn't going to be used immediately will get the circuit that it needs, and I will probably run a wire to where it needs to be eg. an electric fan will need a wire near the radiator. Once I've run the wires I'll terminate them with some kind of waterproof plug so that the cables don't get damaged before I need to use them.


I may add to this list and I'll need to come back to fill in current handling capacity so this page will get a few updates before it's done.
