Neat Relay+fuse wiring solutions

PostPost by: mbell » Sat Mar 08, 2014 5:48 pm

Hi,

I need to add a number (~6) relays and fuses to my +2 for the headlights, lift motor, cooling fans, horn. Given the number of relays I've been looking for a neat combined relay/fuse box to mount somewhere in the nose of the car but haven't come up with a good solution.

I was wondering if anyone had any suggestions/recommendations? (preferably US suppliers)

The Busman Box* looks good but requires lots of different connectors, plugs and tools to be bought which seems a little over the top for a single project. There various separate fuse and relay boxes but that a single unit would be better/tidier. I could just use relay holders with fuse support that clip together but with the number of relays I am not so keen.

Thanks,

Mark

Mark, I got most of my stuff here.

I went with the overseas supplier as it was easy to get wire in a wide variety of correct colours. Ordering and shipping was pretty easy.

Same deal with this supplier, although also overseas.

For a US supplier, have a look through these guys web site. Their site is much better than when i was looking. They more specialize in the vintage stuff than what you are currently looking for.

I have bought stuff from all three suppliers with no hassles. The tools required are a good quality crimper, stripper and two small tools that assist in removing the terminals from the various blocks. I used very few soldered or bullet connectors.

Your choice of course, but I ended up mounting the fuses and relays in the glove box. The advantages of this approach are that it stays clean and dry, and most of the complicated wiring is contained to the dash which can be easily removed with several additional modern connectors. Mind you, was totally rewiring the car, so figured it was the time to do it.

Mark

Have a look at : www.motogadget.com , they propose a special system based on multiplexage , called the " m-Unit V.2 "which is a very compact unit and is able to manage a lot of function.It simplify a lot the wirings You neeed no more relay . It is originally build for motor bikes so , it is very strong and waterproof . So , why not for a Lotus ?

I used Hella Blocks.
They make a series that interlock, fuses and relays. Available from many sources in the states. Summit Racing caries them I believe.

I got mine here:

Thanks for the input and comments. Looks like some more investigation is required.

The "m-Unit V.2" looks like and interesting box of tricks but probably more suited to a full re-wire rather than the updated to the front-end wiring I am doing.
