Tidy way to organise switched lives feeds?
paublo999 - 12/2/12 at 08:20 PM

Hi

As per title, I am rewiring the MNR and previously had various live feeds hanging off the back of the key/kill switch. Can anyone suggest a tidy way of taking a live feed and distributing it to various circuits?

Also can anyone suggest an immobiliser or way of immobilising a 3rd party ecu without removing the ecu. An FIA kill switch is fine for a race car but I want to remain road legal. Any advice appreciated as wiring isn't my bag

Cheers

Kill switch, to a relay, to a bank of fuses - I have a 40 amp relay switching on 6No fuses.

A Toad Sterling will be ok for immobilisation.

A 6/8/xxx way fuse box with a "bus-bar" type arrangement soldered to the input side so a single live feed on the input side, feeds all the outlets.

Thanks for the replies, I hadn't considered a second fuse box.

How would the pro's do it or on a race car to maximise reliability?

You must be able to get a unfused distribution box of male spade connectors? Otherwise can you not crimp 2-3wires into one connector? How many switched feeds do you have coming off the ignition and for what?

I would certainly agree that a stack of piggy-back spade connectors hanging of the back of the switch (we've all see in done) is not the greatest plan!

Not a fan of soldering either however.

try here http://www.vehicle-wiring-products.eu/VWP-onlinestore/connectors/connectors.php#box about half way down the page are a few different types of distribution/terminal blocks

When u say remain road legal, there is no reason why an FIA kill switch isn't allowed on a road car. its just not accepted as a suitable immobiliser for IVA. You can retain it and add a typical electronic immobiliser as well.

If you have mechanical anti theft devices an electronic immobiliser is not needed is it ? Does an immobiliser have to be passive arming to pass IVA ? This kit from Falcon should be enough to do the job I think.

Yes, thats right it doesnt have to be electronic, its worded so you must have an ignition switch (A key operated switch normally used to start the engine.) AND is permanently fitted with an anti-theft device OR an electronic immobiliser.
The mechanical part can just be the steering lock, so keep the donor key switch and column and you comply.
Not sure what you mean by passive arming. do you mean it automatically activates and deactivates? in which case no, it can just be key fob activcated switch or one that is 'sensed' conactlessly.

Exactly what I did. Bought a outdoor fuse box thing from Screwfix for a couple of quid and a Bus Bar from ebay. Going to sit it inside the scuttle. Mines a permanent live setup though. I want a few things on Plive such as a 12v outlet socket and cooling fan etc

I used the marine type fuse box with pos and neg bus bar, screw fit terminals in and out.
Neat, compact and reliable.
6 to 12 fuses

Cheers all. Happier Wuth the options.

Ordered a toad immobiliser and been looking here http://www.iem-services.co.uk/search.asp?types=yes&type=Auto+%26+Marine+Electrical+%3E+Bus+Bars
