If you are wanting the spots to activate in conjunction with your main beams after the fitting of the boomslang loom I simply used the now spare headlight supply socket to trigger the relay for them whilst taking a fused feed from the alternator. This kept all the circuit for the spots under the bonnet without having to add cables and switches into the cab. 90 wolf - Jasmin http://www.defender2.net/forum/topic39408.html

You definitely want any feeds from the alternator to be fused as close to possible to the source.
Bluesea do some very good bus bars that are well made and will last. Especially with tinned lugs etc. (I've found Selterm there in the States to be very good). If you wanted a better headlight solution I would recommend the Land Reiziger loom more than the Boomslang due to having two Relays. One for the dipped, the other for main. In mine I swapped the Relays out for Relays with a diode across the coil. (Check pins are correct, on mine the trigger and ground needed swapping around).

Thanks for the info and recommendations Steve. Whatβs the advantage of the diode equipped relays? |

I fitted a positive busbar in the rear of my USW to feed a variety of lights and sockets. I used an off the shelf busbar and mounted it in a plastic box:

That looks a very professional set up LRA! Food for thought! Much appreciated, thank you

They're latching relays. They're actually due to be swapped out at some point, as they don't work very well with the LR buttons that I'm using. It's the fault of the buttons rather than the electronics, though, but as I'm keen to keep the former another solution is called for

In answer to your question they (Diodes) across the Relay coil would help suppress voltage spikes or fly back voltage spikes up the power source wire. In a Relay they suppress and dissipate. When used in-line forward biased they voltage block return voltage.
Dissipation is better than blocking alone, and is better for relay coils longevity. Particularly important with more sensitive electronic, as the return voltage spike could cause damage.

Click image to enlarge LRA, that bright metal plate? Is it stainless steel? And is it an earthing plate? Does it perform satisfactorily bolted to the aluminium wheelarch? |

It's a piece of aluminium and yes, it does provide an earth point. It's fixed to the wheel arch with a speed screw and so makes a very good connection. Darren
