so i got a scion tc and i bouht 3 rocker switches for the switch panel to control different lights. the rocker switch i have has a led on it too. so ont he back naturally their are 3 prongs. one for a hot wire, another for a negative and a 3rd that i dont know how to or where to wire it up too inorder to get my little led ligth to work on the switch. please let me know

 

On my switch one outside prong is for Ground, the other is for Power and the middle was is for whatever you're sending power to.

Ground - to piece of metal
ACC - to lights, etc
Power - to fuse/battier/etc

 

ground as in the metal on the car?

 

i have one prong going to te battery, another prong for the actual device witht e swtich between them but the 3rd what do i hook that up too get my led to work?

 

In the picture is my tapped fuse, and off to the right is a little screw that was sticking out, I just wrapped my Ground wire around that.

And here's the switch I used:

 

i got pics
heres the actual switch with led...


heres the back of it...

the prong on the far right is the one that leads right to the neon tube, the one in the middle is the positive charge from the battery. now the thrird one on the far left im sure is for the LED but ive tried different combonations to make it turn on but it just wont. help me

 

The LED is built in to the ACC I believe (to the neons) so when you turn the switch on, the LED also comes one.

Works the same way on my switch. Basically the prong you don't know what to do with is the Ground.

 

it doesnt make sense. i have it wired to the battery through the switch to the neon tube. but i tried putting a 12v charge to the 3rd prong, no charge, i even grounded it doesnt turn on im missing something doing something wrong

 

Do you have Aligator Clips?

If you do just clip everything to test it.

The middle prong should be your ACC, and one or the other end progs should be the Ground and Power, so just try switching the wires to see what happens.

Oh, ha... and is your power source constant, or do you need to turn your car on?

 

i have tried switching everything around. no the switch is hardwired to the battery.

 

Could you take a pic of everything wired up?

It took me a little while to get it all figure out too, so don't worry.

 

whats acc?

 

heres the 3 prongs. 1 to the battery one to the neon tube and the third i cant figure out.

 

By ACC he means the neon tube you are going to turn on with that switch.

You have the tube hooked up to one prong.

You have the battery to another.

Basically, all you need to do now, is hook a wire up to that third prong, and find a place to hook it up to something metal on your car. That will ground it. That is what the 3rd prong is for.

 

ive gone in and tested the circuit. their seems to be no power after the little led but all before it their is. it seems the led isnt letting power go past it?? what would that mean bad led? that would mean i bought two defective switches? witht he same problem? im so confused

 

Again, the third prong is your Ground.

Take a wire and connect one end to the last prong and the other end to a screw or something metal close by.

That should do it. If everything turns on then it should be fine, if the LED doesn't but everything else does, then don't worry.

Get the important stuff out of the way first, to make sure you've gotten it all right. If it turns out to be a defective switch, then you know it's just the switch.

 

yea i tested the ground and it didnt work. so im gonna pick up 2 new switches. what boggles my mind is i bought two bad switches. thats wierd. where did you get your switch? and does it fit clean right into the switch panel or did you have to modify it to fit.?

 

I got my switch from RadioShack, and it took some modifying of the old insert to get it to work.

 

lol, ok, the sad truth is that thoes switches do look nice, but they dont always work, alot of the time they will work innitially and just randomally stop right after, its a crap shoot getting one that works correctly, but i have taken a chrome one apart before and replaced the led and manually wired it to the headlight switch so the led is on whenever the headlights are... but that was alot of work for a cheap little part, it does look cool tho

 

think youd be willing to make two for me if i send them to you?
