Thanks David, that's a very clear diagram. And quite usable as a PDF on those 4 pages, too!

David,

Just looking at the diagram. Very useful as I to am going to be making my own wiring loom.

One thing I did notice is that you don't have a fuse in the permenant feed for the hazard lights. I think in the original Sierra loom there is a 10a fuse in this feed.

Cheers

Dave

Megajolt has 7.5 amp fuse also check Edis, this should be on a separate fuse.
If the Megajolt fuses or fails the Edis will provide 10 degs advance for limp home

Thanks for the further feedback everyone. Wil try and update the drawings soon - I been busy on the car over the weekend and will be tonight so will squeeze in some time soon.

Davedew - must admit I hadn't thought about fusing the Hazards. I think I could simply do this taking a branch off the Horn/fan.

Snapper - as I'm using a hard rev limiter with the Megajolt, the coil power is controlled by the megajolt itself. Hence I figured that if the fuse was to blow to the megajolt, then you would also lose the coil power and you couldn't use the limp home feature of the EDIS module - hence the single big fuse - whether this is the correct assumption - I'm not sure !!??

David,

Your going to shoot me.

Just been looking through the IVA manual at the parking light section. I think that you need to swap your ignition switched supply for the sidelights to a permenant supply to comply with the regs.

Cheers

Dave

Nah - that's far to kind

Seriously though it's great to have lots of input and feedback from people - better now than in the middle of the IVA test.

On the parking lamp subject (section 30 IVA manual) - I read it as they are optional on vehicles below 6m long and 2m wide, which the roadster is. If you do have parking lamps, then you must be able to turn them on without the key in.

That would suggest we don't need them. What does everyone else think?

Just looked at it again. The table seems to indicate like you say that they are optional on vehicles under 6m long.

Ignore me then. I wont mind, the wife does it regularly!!

Cheers

Dave

6M... I thought Class M was just for cars,

I think the longest UK production car was the AM Lagonda at about 17'4" (6M being 20' ! ) well it was when it ceased production in 1990.
