All good.
I only hope someone does it for me when I mess up.
quickly played with that diagram thats been floating about. Thats my understanding how it would be.
Switch in one position, lights will be on.
Switch in the other position, will come on with reverse lights.
Always powered through the relay.
Remember to fuse the relay and the power to the switch.
Thanks heaps, this will make it nice and easy for e to work out how to put my roof lights on , looks like I can start my project today
always good to see someones work pay off. Spend so long doing it its good to see it done right. good job mate.
Gday, just joined the forum after reading this post and many other helpfull ones! Im just about to run the wire for two 7 inch cibie oscars with 100w globes as rear work lights and also flip up when out bush and would firstly like to say this post has helped me out heaps. Just want to know if my thinking is correct, i have a 5 pin relay and will be running positive off each light to each 87 pin on the relay, does this mean each wire will draw aprrox 8-9 amps per light instead of 16-18amps on one 87 pin (4 pin relay)? Then run one wire fused from battery to relay, one wire from relay to negative on battery, one wire from switch to reverse circuit, the other switch pin to the same pin on relay as reverse curcuit, then the relay will take all the power right? Then i will have the middle position of the switch as off, one way on for light only when in reverse and the other to have on whenever nessicary and dont need the ignition on? ill just put what im running and please feel free to correct me if i went wrong, narva 6mm(30amp) wire inline fuse holder with 20amp fuse, 6mm wire, 40amp 5 pin relay with resistor, 20 amp 3 way switch.
Sounds about right but I like pictures when it comes to planning wiring stuff.
The last wiring diagram looks good to me, I'd follow that.
Unless you're close to the battery I find it a PITA to pick up the earth there, I'm lazy and look for a decent earthing spot closer to where I'm working, generally speaking......
Cheers
Drew.
what do you mean by PITA? is it point in the area? relay is going right near the others near the battery, as there is a spare threaded hole for an auxilary relay, just had a look under the bonnet this arvo after repling never realised it had 2 other fuses and no where near the quality i am putting on, just bought the car so might consider putting a multi fuse box in.
PITA is a FLA for Pain In The Ar....Quote:

Then connect the reverse light feed to one side of the switch and the battery feed to the other side of the switch. As per the diagram above. If you are going to take the battery feed for the switch from pin 30 of the relay I would recommend using a 5 or 10amp fuse mounted as close as possible to the relay.Quote:

Thank vendor, Thanks heaps just knocked off and getting in to the wiring now hopefully I get it done this weekend
