Just about to start the wiring at the weekend - having looked over the diagram and picked up a new fusebox I have spotted a way to ease the wiring. I have moved the fuses for the fuel pump and ignition circuits to the other side of the relays so they are on the permanent live side. I have also moved the order of the fuses around in the fusebox so that they are grouped by their feed. The fusebox I bought has a busbar with it that can be cut to size so by grouping the fuses together I can run a single wire to each grouping.

I've attached a copy of the latest diagram along with the fusebox and relay listings.

Cheers

Where did you get your fuse box from? Do you have a part number or picture of it.

Thanks

Dave

I bought one of these -

And got one of these busbars to go with it -

Thanks for the links, most appreciated.

Brilliant work David,I could be losing the plot here but talking of parking lights is it possible to do as VW does and use the indicator switch for them with ignition off.

As originally wired - i.e. if you take the column and wiring out complete - the lights work off the permanent live circuit. I.e. the sidelights will come on regardless of whether the ignition is on or off.

I have made the decision to modify this so that the sidelights will only work with the ignition on. This means that if the car is parked up and anyone 'plays' with it they cannot leave turn the lights on.

I also realised at the weekend that the sames applies to the cooling fan over-ride swithc, which should be fed from the switched live rather than permanent live to stop people messing with it. I will update the diagram to reflect this when I get a chance.

The only items that can be 'switched' on with the ignition off in my circuit is the horn and the hazard lights. Everything else requires the ignition on.

Hope that makes sense.

I see what you mean David,in the case of MOT the sidelights must work with ignition off as must hazards and to be honest I have not looked at the IVA regs so it may not be needed.

Cooling fans mostly work independently of ignition as the idea is to reduce the rad temp,cutting the feed would defeat the whole object of cooling the system and could lead to overheating.

Nice work.

The lights on my girlfriends Fiat only come on with the ignition

I knew that was coming and thought about it later, and I have tested loads of them unfortunately.

Got my wiring connected to the battery today and the main beam kept coming on with the dipped beam. I spent 2 hours trying to sort it, tracing back the wires, but they all seem to be as per diagram. I unplugged the fog relay and it sorted the problem. Is there more than one type of 5 pin relay? Or could it be the diagram?

Hope someone can help.

Cheers
