I have a '87 camry and want to install fog lights using the signal lights housing. I sawed off the signal light bulb socket because it was connected to the housing. I drilled a hole in the corner light on top and used the corner lights as signals. Now I have empty signal light housings and would like to use them as fog lights. I am planning to get the bulb sockets from the junkyard from a maxima or something,anything i can find. I just want to know what parts i will need and how to install all the wires, relay, switch.

I bought a rocker switch that is rated 25 amps with 3 spots that the wires connect to (load, power, ground), a 40 amp relay with 4 spots that wires connect to (30, 85, 86, 87), fuse holder that is rated 15amps, and have 2 h3 bulbs and connectors.

I followed the diagram in the picture i uploaded and it doesn't work

 

If that's the case then it should work. Diagram requires low beam or high beam be on to work. How many amps do the fog lights draw?

 

I tried it without connecting it to the headlamp wires maybe that's why it doesn't work. Im not sure how many amps does it draw cause its just 2 bulbs. I bought 18 gauge solid wire from radio shack and I think i bought the wrong one.

 

That's why it doesn't work.

As long as the two bulbsdon'tdraw more than the 15amp fuse from battery. 18gauge rated for about 16 amps. For me it would have been marginal. I'd research amp draw of bulbs.
Amps = watts/volts(12)
