Ok so have sat for a few hours and came up with this. Its a bit rough looking and colour codes of cable are just their for my design purpose at the min, they will change.
I might be misreading your diagram but are all the X's relays - if so I think you should lose the ones on the stop lamps, indicators, fog lamps, horn, dash lights...just adding something to go wrong and they are fairly low load circuits....
Rear fog light needs a tell tale light either on the switch or dash MOT requirement.
As previous post I agree those relays not required , just complicates job cheaper to buy a good quality indicator relay from "vehicle wiring products"
Also check whether two fog lights legal , they must also be know more than 900m high from road fro memory
shouldn't starter be on position 3 and the relay to the 12v to fuse box on position 2?
I'd personally also put heater plugs on position 2 and use position 1 for things like stereo / cb
Emergency flashes / indicators - defo put them direct to battery ,you don't want them only operating on a key as if you break down you need to leave them on and walk away from the vehicle with the keys on you.
I'd personally also put side and brake lights on permanent live - again side lights for breaking down at the side of the road at night and brake lights... just because i've had a total power failure before and having the brake lights on permanent meant the person behind me could see i was stopping
and as mentioned above - too many relays, you're just adding failure points! sensible for head lights, etc. but not for everything.
Yeah will do. It's long way down the line. Need to get my engine and gearbox mounted first. But won't be rushing to whack it all together. Everything will be tested and double tested before a battery goes anywhere near it.
I got a new indicator stork from Craddocks recently for a few quid when I broke the wires off the old one. Isn't great but worth buying while you're at it. They should be good for a fair bit of current. New toggle switches are available from plenty of places.
If you want to test lighting circuits a "lamp limiter" isn't a bad idea. Basically put a high-ish wattage lamp (I use a lucas sealed unit) in series with the battery then test the load points with low wattage sidelamp bulbs. If you have a short somewhere the limiter will glow bright and the load lamp will be dull...saves on burnt wiring...
I'd stick in a reverse / work lamp at the back too while you've got it in bits. Depending on the model there should be a hole ready to take a brake light switch on the gear stick base, otherwise a dash toggle - though I'm not sure but you might need a repeater in the cab if its manual. Makes reversing at night a lot easier...
Good work by the way! I'd have a go at trying to keep the wiring colours the same as on an original as it might save you grief in the long run. I've swapped only a few wires in mine but the ones I've replaced for different colours catch me out every time!
