Perimeter Lighting

[PARAGON]

I replaced my DRLs a good while back and put some fogs in replace of them. When I did this I lost the front part of the perimeter lighting. I haven't studied the service manual yet but does anybody know an easy way to tap into something so I can put a relay on it and get the headlights or my fogs to come on when the perimeter lights come on? There is some circuit that tells the backup lights to come one but I am not sure where that might be.
