Can anyone elaborate on how you wired fog lights into the ignition switch so they operate with the switch please let me know.
pictures would be great. Thanks

Re: What is the process of wiring auxiliary lighting
Assuming you're talking about halogen fog lights, you don't really want to put that load on a switch that wasn't necessarily intended to switch it. The best thing you can do is to wire a 30 or 40 amp automotive relay so that it is switched by the ignition circuit. Then run a (fused) wire directly from the battery, through the relay, to the lights. Position the fuse as close as possible to the battery, and make sure the fuse is the smallest value that will run the lights (if you tell us the wattage of the lights, I can tell you the fuse size).
That way the only additional load on the ignition circuit is the relay coil, which is miniscule. It then switches the large load of the lights on and off.

Re: What is the process of wiring auxiliary lighting
Thanks for the information. I'm really good with mechanical things but not so much with. Electronics. Do you think you might be able to go more in depth with your directions. Like supppper dumb it down you can use crayons to draw pictures for me lol....thanks

Re: What is the process of wiring auxiliary lighting
A standard automotive relay can be used to switch high power (30 or 40 amps) while requiring only a small amount of power to actuate the relay. This way, a small switch can actuate the relay, and the relay actually switches the lights on and off.
Here's a diagram using a standard automotive relay:

Re: What is the process of wiring auxiliary lighting
also if I may humbly suggest, put the lights through an off on switch on the handlebar, this will give you more control should you need them off for some reason.
if the 1500, is the same as the 1200, there are auxiliary screws situated above the fuse box, that activate, when the key is turned on, this may be easier to access for the relay trigger wire, than tying into the ignition switch.
