Splicing my fogs

so i am reading all the write ups on the DIY oem fog lights, and i am trying to splice my fogs into my low beam headlights so that they go off when i put on my high beams. but keep blowing the bulbs when cutting them on but the fogs do work spliced into the low beam wire, just blowing my headlight. can any one help me figure something out.

 

thanks

 

You can not hook the fogs directly to the headlamp circuit. You'll overload it and blow fuses all day long.

You need to use a relay and power them off of the battery, using the low beams (or parking lamps) as the trigger source for the relay.

Most 30 amp automotive relays have 4 poles....#30, #85, #86, #87.

Wire it up this way:

#30 (+) to battery with a 15 amp fuse as close to the battery as possible.
#85 (+) to low beams or parking lamps.
#86 (-) ground
#87 (+) lead to foglamps

If you want a switch to defeat the fogs completely, just place it on the signal wire (#85).

 

hell yeah that sounds like a plan to me. Thanks! will let you know how it goes

 

gave it a try but for some reason lights arent coming on. any sugestions on what i may be missing. i did everything the way stated.

 

did you grounded both the lights and the relay?

 

yep. but its all good had one bad connection that i found got em working about an hour ago. great mod!

 

Thanks man this really helped me alot!
