You should be able to. You'll need to find the wire that powers up the fogs and connect a relay.

The only problem you may run into is that the car probably requires the fogs to suply power to the fogs. It may be more trouble than it's worth. Would be easier to connect your headlights than the fogs. If it's aftermarket fogs you should be able to do pretty easy. If their factory it's prob not worth the effort unless you've got lots of time on your hands.

Wire it up like this, assuming you found a +12 volts wire when you used your DMM.

If it was a negative wire connect pin 30 to chassis ground.

85= +12volts

86= Trunk/channel 2 wire from alarm system( should be -12 volts approx 200ma )

30= +12 Volts constant

87= Fog light wire you probed.

87A= Not used.

Same as the relay below.

Good Luck

depending on your alarm. may have to reprogram, that is it can be done, most ch 2 only stay on while the button is being pushed. most dei can use ch 3 or 4 and change the progam so it stay on for a lenght of time or unilt u hit the button again. what ckind of alarm do you have?

Good call swamp rat, I forgot to mention that way he'd have to hold the button to keep 'em on.

Otherewise look at the relay section and build the relay pack to convert momentary to continuous. click herehttp: //www.the12volt.com/relays/relays.asp
