Fog light wiring help

Xtra Big Kahuna · 10-31-2011, 10:11 AM

Okay so I installed some autozone fogs that just went right into the battery and now when I run them the alternator runs. Is there a way to plug them into the existing fog light connectors so the alternator wont run?

The alternator runs whenever the engine does.

So, you'll have to be a bit more specific.

When ever I turn on the fogs you can hear the alternator start to whine

What i did was just splice the wires from those autozones into the original harness your comes stock with.

Is this the only time when you can hear it?

Xtra Big Kahuna · 11-03-2011, 12:30 PM

Yes this is the only time I can hear it. I was going to tap into the stock fog plugs but I dont have the stock fog light switch

I would double check how you currently have things wired. Make sure there is a decent connection to the battery.

I cannot advise you to hook them up to the stock wiring w/o knowing their power. Anything over stock 55W & it would not be advisable.

Do you hear the actual alternator itself whine, or alternator whine in the speakers?

why not add a relay? Seems your light is drawing too much current.

Xtra Big Kahuna · 11-05-2011, 01:14 PM

I have a relay. They are either 65 watt or 55. Can't remember which. And it is the actual alternator whining.

Can you turn the fogs on w/o other lights? If so, does it whine w/just the fogs?

I'm thinking you are tapped into something you shouldn't be.

Xtra Big Kahuna · 11-05-2011, 11:18 PM

I can turn the fogs on and off when I have my headlights on and it only whines when I have the fogs on for an extended period of time. Like 10ish minutes.
I have the fogs wired directly to a relay which is connected to the battery and a switch inside the car.

Are you running ICE? How healthy is the batt?

ginobendezu · 11-06-2011, 09:30 PM

i got my 4inch fogs spliced to my drl. so they come on as soon as my car starts ( i do nt have stock fogs)

Xtra Big Kahuna · 11-06-2011, 11:35 PM

What is ICE? Im not sure about the battery. Ya mine are just hooked to a switch and can only come on with the parking lights or headlights. Kind of a bummer sometimes. I will probably rewire them soon

ginobendezu · 11-07-2011, 03:51 PM

did you tap into a power cable? i dont have mine wired to a switch, figured it doesnt matter if they are on full time since it'd be safer

Running a stereo/amp?

The switch is tapped into the cigarette lighter and I am running ICE. Its only an aftermarket head unit with the stock speakers I believe.

If that's the case, you should be able to turn them on at any time.

Xtra Big Kahuna · 11-09-2011, 10:38 AM

Its tapped into the light for the cigarette light

The solid Green wire I hope?

Xtra Big Kahuna · 11-13-2011, 09:38 AM

yep.

ginobendezu · 11-13-2011, 09:13 PM

hows your alternator/ battery. your battery could be kinda weak so alternator might b kicking in. idk if it might work like that but im just guessing.

Xtra Big Kahuna · 11-13-2011, 09:38 PM

Im guessing my battery may be a little weak. I just got the car about a year ago or less from a dealer and I doubt they would swap a new battery in. How would I check the battery. Sorry I am not much of an electrical guy.

**2way** · 11-14-2011, 04:45 PM

If its the original..... its time for a new one.

Xtra Big Kahuna · 11-14-2011, 04:51 PM

I have no idea if it is the original. All I know about it is that it is from AC Delco.

rg3777 · 11-15-2011, 06:17 PM

I doubt anyone has the original battery. If it was it would say Toyota. AC Delco is GM. You need a volt meter to test the battery. It should be reading close 12.5v to 13v when off and about 13.5v to 14.5v when the engine is on. If it is under 13v when the engine is on it means it is not holding a charge and will die soon. Especially if you listen to the radio with the engine off for a long period of time.
