Hello everyone i need a bit of help and think this is the correct section.
I want to install front fog lamps to my car, but want them to turn on and off using a oem switch. The switch i will be using is a momentery type. So if i hold my finger on the switch the lights will turn on. But once removed they will turn off again.
Is there a way to turn the switch into a latching type ? and still turn of or reset the switch when the power source is turned on and off. IE power from the side lights.

Is there a simple pre built module or a way without using loads or relays and stuff.

Thanks gary

I did not post any info about my car because this should be the same as any other 12v car system.

Use this diagram. Connect the "Fused Constant 12V" to your desired power source. (Side lights). I don't know of a module. These relay arrays are kind of cool to build. Every time you activate your fogs, you'll think of all those relays doing what you wired them to do.

How much power do the fog lamps draw? A DEI 611T in latched mode might work. May have to have the 611T trigger an additional relay depending on power of the lamps.

Sorry about that. Here it is as an image. Remember that the "Fuysed constant 12V +" is connected to your side markers. When the markers are turned off, the array resets to OFF. If the fogs draw more than you wish to supply from the side marker circuit, you could add a fifth relay to switch the fog current. Wire as follows:

85 = Earth
86 = 12V output from array relay on far left.
30 = Fused hot at all times.
87 = Output to Fogs.

Each lap has a 55w bulb. I was intended to use a single relay was not going to wire directly to the side lights.

Testing a 611T now...Normally open, latched, negative trigger. Red to switched power, Black ground, Green negative pulse in, Brown battery power, yellow positive output to bulbs. Triggering will latch, unlatch output. Removing switched power, output turns off with decay. Reapplying power within about 7 seconds relatches output. The 611T has a 7.5 amp fuse on the output.
