Hello Everyone

Well I haven't forgotten about the work in progress - just had a long weekend down in Torquay :)

I've now updated the latest V1.3 of the wiring diagram. Now includes a new relay switched +ve supply.

I've also added a second document - which lists the fuses, relays and wires to the front and back of the car. As always - please have a look over the diagram and the 'equipment list' and if you have any comments please let me know.

David,

Wiring diagram looks spot on. The equipment list is really useful, but I was wondering what size cable you will be using for your main feed to the master 200a fuse, and from there on to the relays & circuit fuses. Supplier info on the equipment list is ideal.

Cheers

Dave

David,

That’s great, thanks for your hard work.

The pdf’s are now saved in my Roadster folder.

Cheers Ginge

Thanks for all the kind comments.

As it happens I am currently putting together a shopping list for vehicle wiring products for the various bits I will need. If it is of use to people then I'm happy to post it up here.

Having a quick look at VWP now - I willprobably use the following -
battery to starter - 315/0.40 11.8mm OD, 300 Amp cable
Battery to megafuse - 315/0.40 11.8mm OD, 300 Amp cable

From the megafuse to the fuse/relay box I'm not quite sure what to do yet. If anyone has any ideas it would be much appreciated.

A quick thought - would it be possible, or even practical to run battery cable to the fuse box from the megafuse, then split the strands into bundles to go to each fuse spade terminal, then finish off by heatshrinking the lot to cover it all.

Second alternative would be to get something like this


and then use some trailer cable to go from the distribution box with terminal rings, to each fuse.

Look at VWP's modular relay/fuse box.

David,

I would have thought your second option was the best and most professional. Pairing out strands from a bigger cable would be quite difficult to ensure you got enough to carry the current.

I was looking at the vwp catalogue earlier and saw the distribution box that you have pictured. I would have thought if it was mounted on the reverse of the bulkhead under the scuttle it would be fine.

Cheers

Dave
