Not exactly new or innovative. But here's a 'how to'. Hopefully someone will find it helpful. Relays. I personally use one relay per lamp. This will stop any possibility of overloading them. 12V 30Amp is recomended. And you should have a pin pattern something like this.
Next to each pin is a number. 30, 85, 86 & 87. These numbers relate to the connections shown.
Depending on the number of lamps you are using, you will need to connect the relays up in series. Use proper crimp connectors.
DON'T use bare wires or insulating tape.
a/ You won't get a good connection.
b/ You'll probably set fire to your pride and joy.
DO use suitable cabling. I've used 30Amp cable for the feeds and 15Amp for the earths
Think carefully where you want to locate the relays. Take the following into account.
1/ Keep away from direct heat. (Exhaust, Turbo, Engine etc)
2/ Keep as dry as possible
3/ Closer to the battery the better. (Avoid long cable runs)
This picture shows the relays bolted to the battery tray surround.
Note the inline fuses. I've used one fuse for each pair of relays. (15Amp)
You'll need to find a suitable earthing point for the relays. Here, I've used the bolt that secures the windscreen washer bottle filler.
Wiring the lamps in. Again. Make sure you use proper crimps. Twisted wire and sellotape or even insulating will not do. (There's plenty that have found out the hard way.)
In this instance I've used bullet connectors. This will enable me to swap over any damaged lamps with the minimum disruption.
I think the following pix speak for themselves.
I've used cable ties to keep everything tidy and manageable. The sheathing for the main loom is clever stuff. Bit like snake skin in that it stretches. Don't know what it's called. I got a few metres from an auto electrician mate to try. I'll try to get more info. But it makes things very neat & tidy.
Mounting the lamps and routing the loom. Obviously you should have worked out where you want to mount the lamps. (Bull bar or bumper) But the main concern is routing the cabling. Again you are looking for the most direct route, this will keep cable runs as short as possible. Look out for sharp edges where the cable could chafe, I removed the front grille and fed the loom into the headlamp aperture. Which brings it out under the radiator expansion tank.
Once you've done that. You'll need to connect the loom to the relays. I've again used the washer bottle bolts to earth out the lamps. I could have earthed them on the bumper, but chose this as it makes things neater. No wires dangling around to get snagged.
Refit the grille, secure the relays. Step back and admire your handiwork.
Hope this helps.
