Hi all electrically minded people I'm in the process of adding a few relays to my MGB to help take the electrical load off some of the switches, so far I've got one for my spotlights but I'll be needing two for the headlights, possibly another one for the horn and one for the electric cooling fan. At the moment the one relay I have takes its main power feed from a wire that goes to the terminal on the starter solenoid but theres not a huge amount of thread left on said solenoid to keep adding ring terminals to feed each relay. So is there a product out there thats like a box that I can put all my relays in, have the one main power feed coming into the box which then splits to each relay but I can then add the various other wires myself? I'm thinking this would look a bit neater than having a row of relays on the inner wing with a ton of wires all heading down to the starter Any help is appreciated, Cheers

Two ways really, just bear in mind how you're going to fuse them. You could take a feed from the solenoid and daisy chain (piggy-back) using crimps like this: You'd need to use fairly chunky cable and appropriate sized crimps throughout. Also, the outputs would need to be fused. Alternatively you could use a fuse board for distribution. Take the feed to something like this and distribute the power from the fuses to the individual relays.

Cheers for the links to those sites guys, they all seem to do a similar sort of relay box which I'll probably go with.
Just need to find a tidy way of splitting the input power really, I could use a load of piggy back spades and in line fuses but its a bit messy. I do like the look of that fuse board though, would solve any fusing issues too

For splitting the power across different feeds you can use a distribution block or bus bar, such as these: www.12voltplanet.co.uk/power-distribution-posts-blocks-busbars.htmlJust connect the cable from the starter solenoid to one post and then run the cables to the relays either the same post (single post) or other posts if you get a multiple post one.

Thanks for those suggestions too guys, I've gone for a fuse distribution board like the one sam1990 posted so I can have the power from the solenoid go to that, then I can take fused power to a standard relay box Thanks again

This is how the OEMs do it. One wire supplys many relays

I cut these off cars and use them later on my projects.
