fog light, alarm, fuse box

Hello gentlemen, im currently wiring up a set of after-market fog lights on my 95 civic. An issue that arose was when i had to wire my fog lights into my fuse box. Attached is a picture of my fuse box and its layout. It is stated that during the installation of the fog lights you are to wire them to Slot D on the picture. Now i already have a plug in there and that is for my car alarm. If you look on the picture you will see an index labeled ; Option Connectors Index It gives you all the specifications. The question i have is... if i move my alarm to lets say slot A for example, would it effect my alarms functionality? Because with that specific slot D it says ; Hot with light switch, in the HEAD or in PARK. as apposed to slot A; Hot at all times Thanks an advance for any help !!!

sorry i forgot to ask.. or another option, is can i just add the wire to that slot?

Is that under dash? Why go there? Not that fog lights are a big deal, but I tend to use relays for all lights. Hence battery - fuse - relay - light(s) as direct and short as possible. But if there is pre-existing wiring for the lights, ok.... (My car is old. Most former hi-current carrying wires have now become mere signal wires.)

Oh just use an illuminated switch, feed it off a low beam headlight circuit from the steering column loom to 86, ground to 85,20amp fused to 86 and output from 30. Feed the output to a second relay at 87, ground to 85, ignition to 86 and lights output from 30. This will give you LEGAL lights and an auto shutdown when you turn off the ignition. The second relay is optional.

Well what im trying to do is have a separate switch for my fog lights, so i can have the ability to turn them on & off whenever i please without it effecting my HID's

So that's what we both suggested. Wiring the fog lights separately is: a) Illegal in many countries, they can't bew legally used in Europe without the low beam headlights. b) The extra relay means you can't leave them on. Q. wth has this to do with DRLs.

Here is a picture of my setup what i was thinking was.. what if on the relay i leave everything as is the Switched Out wire to my fog lights which are in parallel the Coil out is grounded the Switched in is a 15A fuse connected to the +ve on the battery & the Coil in is run to the switch -- and on my push button switch in the car.. i have one connection grounded the other connection is connected to the switch( Coil In) & i was thinking of running a separate wire from my battery with a 15A fuse in line directly to the switch so it has power. so every time i push the button in, it has power.. does that sound right? or am i missing something?

My guess would be that that is how the alarm controls your parking lights. 

The first thing I would do is simply unplug the D connector and see if the alarm keeps working.  My guess with what you have given here is that it will, but it will no longer flash the parking lights.

If that is the case you could then connect both harnesses together and power them both off of "D".  This would allow you to use both options and to have both options installed per manufacturers recomendation.  it sounds like, though, that if you install it this way then the fogs will only kick on with the parking lights.

But if i was to add to connection D.. wouldnt i have to upgrade the fuse itself? because now it has a higher load on it

According to your diagram above you will be adding roughly 160mA to connector D - I think you'll be OK.

Basically, what you are doing, is taking the output that is ON when your parking lights are on and running it through a switch.  The switch then controls a low current relay.

The current for your fog lights will be provided through connector B.
