Well i messed mine up, was old wires, and half of them are broken (that actually wasnt by me haha)
I thought i would just take out the wires and rewire completely, making them easier to get to ect, ect.

Never wired fog lamps before (or even much at all)
Whats the easiest way i can do it, and make them turn on with a switch.

And i don't want any temporary ways, and to be honest, as long as i can follow and easy guide, difficulty isnt an issue,
Thanks guys

Ok then. Now are we talking spot (or driving) lamps or fog lamps.
Spot lamps need to be wired to come on only with the main beam headlights, whilst fog lights are for use with dipped beam headlights in conditions of reduced visibility where visibility is less than 200 yards. So the foglights have a single on/off switch, whilst the spotlights are wired from the headlight main beam cis=rcuit through a switch which allows them to be on or off when the headlights are on main beam.
First of all you need an additional fuse box with a minimum of 4 fuses ( for 2 x spots and 2 x fogs). You also need 2 off 12 volt relays.
Mount the 2 relays on the LH inner wing. Run 2 power leads from the starter solenoid via 2 x 20 amp fuses to the relays input terminal. Run a lead to the spotlights from the output terminal of one of the relays, via a 12 amp fuse and then to both the spotlights. Now take a signal feed from the main beam warning light and run it to the relay signal terminal via an on/off switch. Run a 12 v power lead from the ign and another lead from the relay earth terminal to the body. That takes care of the spotlights.
Now run a lead from the output terminal of the other relay, via a 12 amp fuse to the foglights. Run a lead from the ignition 'on' circuit to a switch and then to the foglight relay signal terminal. That is the foglights wired.
Use good quality crimp-on terminals and sufficiently thick wire able to take 150 watts as a minimum.
Don't forget to earth the lamps themselves.

try fog lamp wiring ...google

[willava182]

and we are talking about both!
2 fog 2 spot.
Thanks for that guide, i may have to read it 4 or 5 times before i get it though haha
so do both sets have a switch?

i did, and it meant nothing to me

Yes, read the instructions and you'll see that the spotlights have a switch in the signal feed from the main beam circuit to the relay signal terminal. So when switched to 'On', the spots will automatically come on with the main beams heads and go out when you dip (this is a legal requirement).
The fogs have another switch from a feed from the ignition switch circuit so that when the ignition is 'on' and the foglight switch is 'on', the foglights will be on. They must only be used in very limited visibility of 200 yards or less (i.e. in fog or falling snow).

I think i got it,
Would this be a good kit?

and also what is the best wiring guide (picture)
There are so many and not sure which is for which.
Thanks again

I just buy what I need from AES Limited. Don't forget you'll also need a new fuse box and fuses.

"1 x Red Fuse Holder To Battery Wire ( With Fuse )"
Not that? :)

I'm a bit fussy about electrics and I like plenty of fuses. You need one fuse for each pair of lights in the power feed wire from the starter solenoid to the relays, then another fuse for each pair of lights between relay output terminals and the lights themselves. That way a short near the lights can't take out the complete wiring back to before the relay. On my cars I always have one fuse per light and one fuse per main feed wire from the power source. I also fuse the signal cable from the ignition circuit and the power feed to the fog-light switch. You can't have too many fuses.

Alright cheers, ill see if I can make my own wiring diagram that makes sense to me
Cheers

[KernowCooper]

Here is a relay diagram for you to work from, 86 will be your feed in from the headlight Blue/white via a switch you see there and 87 will be out to your lights

Right im confused as ever haha, might just take it to a garage.

[jonnyenglish]

I have to do this soon and I'm not looking forward to it! i bought a similar kit but i didnt realise u needed a new fuse box!!

what box do you recommend?

Thanks
