I have been putting off the wiring as it is a bit of a puzzle as to how it was installed, and quite a hard task.
Managed to thread the wiring through the flexible conduit that goes into the engine bay, and have wired up the engine.
Have utilised a 4mm wire for the charge circuit as it will carry up to 30 amp, also used fabric braided wire over the engine.
When connecting the wire to the oil sender the b%&*#y screw broke, so will have to get another sender unit.
Threading the wired through the flexible conduit took 3 hours, 10 m of MIG wire, 1 roll of electrical tape, 1 can of soft drink and all of my patience.
However, with materials used, should never have a fault with it and therefore, should never have to do that again....
Still have to finish wiring up the rest of it....
