Hey pciley, Thanks!
Sure you can ask!!!!
Actually, I did wire my fog lights to turn on with the parking lights, using the rocker to turn them off if I don't want them on. Ran trigger wire from front left parking light wire to the relay.
The main reason I used a relay was so that I could have the higher amperage go directly to the fog lights, not through the switch. On a previous vehicle, I wired a fused line from the battery directly to the switch then to the lights. The problem I had was that rocker switches tend to get hot when wired this way, so they eventually fail because the plastic becomes fatigued from the heat. This happened more than once, so I know it wasn't the switch. Once I added a relay, I didn't have the problem again.
I don't want to have to replace a $20 switch due to "overheating" if I can avoid it. I know that the Nissan fogs only draw 75 watts (about 6.25 amps), and the switches are rated at 15 amps, but I have have overheated similar switches with about 9.2 amps (pair of 55 watt fog lights). Why take the chance? Relays are a cost effective (about $4) way to greatly extend the life of the switch. The worst problem I have had with a relay has been the contacts sticking (once in about 5 years of daily use). Took it apart, cleaned the contacts, put back together and it was good as new.
The moral to this story.... Relays save lives...switches that is
I didn't mean to ramble on, I just wanted to give a thorough answer.
