fog light ignition

[naruto]

im having troubles with my aftermarket fog lights. This is how i wired it up


and my problem is where to attach it to an ignition soucre. I have tried the head unit but every time i turn the switch on the fuse for the cd player blows(5amp glass type). I'm not sure if i'm supposed to do it but the switch i am using has a built in light and the switch has a male output for ground and when i do wire up the ground thats when the fuse dies.

Also with the ground for the relay i have used a rusty bolt, could that result in my fog lights not working, and does the ground have to be in contact with bare metal?

Sorry if it's abit long but i am trying to be more specific so it's easier for you guys to understand.

Thanks in advance ..Bryan..

When you wire the ground from the switch, you are completing the circuit for the little light in the switch, which takes it over the allowed amperage for the fuse.

You need to do your own circuit for this. Trying to add fog lights to another circuit will just blow fuses.

Using the diagram above (or the one on the box) put a relay in for yourself. From the ign post on the fuse panel (or using a fuse tap), take a fused wire to the switch, then a wire from the switch to ground, and from the other side of the switch to the relay. Then the opposite post to ground. Now run a fused hot wire from the battery across the other terminals of the relay to the lights. That way you're only running a tiny LED and the relay from the ignition source and you won't blow fuses. The lights themselves get lots of clean hot power directly from the battery.

Soooo... i have to tap into a blade fuse from something that only turns on in ignition?

Sorry if i sound dumb not very good at electronics, i also don't want to take it to an autoelectrition just because im a tight arse.hahahaha

just read over your post a few times and i think i get what you're saying. If i find a proper source for the ignition power will that make it work or am i missing something else?

thanks ..Bryan..

Right. The amount of electricity it takes to operate the relay is minimal, so pretty much any ignition-activated fuse in the fuse panel will do. Put the fuse tap on the first side of the fuse so you're not drawing more electricity through the fuse. To find that out, pull the fuse, turn on the switch, and test which side of the fuse socket has power. Use that side.

ok will do thanks man. so it doesn't matter if i tap into a fuse that is 10amps?

[curtis73]

Correct... as long as you tap in before the fuse, that is to say, on the hot side of the fuse.

before? hot side? I stuck the wire straight into the blade fuse slot, but nothing happened still doesn't work however when i leave the switch on then attach the wire into the fuse slot i hear th relay click

terminal 85 and 86 are the terminals that switch the relay. Power to one and ground to the other. If the relay is connected, but its not switching, then you simply are missing the ground or power and need to figure out which one is missing, and why.

ok, does the ground have to be in contact with bare metal?

does that clicking sound mean anything though?

thanks for the help and putting up with my newbieness guys i really appreciate it
