I am installing some ottraw switches for my LED's. And I am supposed to look for the dash light wire.
I can't find the info on what wire this is?
Can anybody help me out? Additionally, where is this wire located?
Thanks

 

Anybody, a little help PLEASE

 

What year is your vehicle and what so you want this wire to do? Provide power to the lights? Provide power to the illuminating LED on the OTRATTW switch? Trigger a relay?

 

Yes, I want the led's on the switches to illuminate

 

When I did mine, I tapped the Violet w/Grey stripe wire that provides illumination to all the switches and gauge clusters. I installed the tap right behind the headlight switch, but you can take it off the dimmer switch too, or any of the illuminated switches.

 

I tapped into the violet with grey stripe today. I am not sure I got any power here!
I do not have that wire in the dimmer???
I had to go buy a multi meter, but I have no,idea if I am doing that correctly (duh)
Do I have to pierce the wire to get a reading?
I took 1 wire off of the tap, then spliced the 1 wire to 3 switches using these

But it was a 4port connector.
Would that work? It works for 110 in my house.
Do I have to take a ground off of the headlight switch also?
If so where do I take that too?
This is so confusing!
This is the switch I am using.

Thanks in advance

 

Some further info would be helpful:

1. How many switches are you wiring up?
2. Are they located together or scattered around the cab?
3. What are the switches controlling?

Referring to the wiring diagram for the switch circuit on your switch http://www.otrattw.com/J66a.pdf

• You should be able to tie pins 7 and 8 together, as described on the switch diagram, and then attached this to a ground under the dash. Look around under your dash for wires that are bolted directly to the body and check for continuity with something you know is grounded. Don't try to ground an automotive circuit by tapping into existing, factory ground wires - it's not like house wiring in that regard. Tie your grounds directly to the vehicle - direct metal to metal contact.
• The violet w/grey stripe wire attaches to pin 6 on your switch. If you do this, then when your lights are on, this wire will provide power to the LEDs in the switch, and they will dim with the rest of the dash lights. If you've already tapped this wire, then you can check this with your voltmeter - you should get some voltage when your lights are on, depending on what the dimmer is set at. Or just connect it to the switch and see if the switch lights up when the headlights are on. That connector from Home Depot is used for residential wiring and isn't for automotive use, but I don't see why it shouldn't work. Make sure it stays dry. There are better, safer alternatives at Autozone, NAPA, etc.
• Power from the battery attaches to pin 2 of your switch (make sure to put a fuse on this wire).
• Connect pin 3 on your switch to the relay you are using to control whatever you are turning on with the switch (aux lights I assume).

There's a member on here named "mamonti" who has provided me with a lot of electrical help. You might try PM'ing him and getting his input on ground locations. He might actually be able to come up with a list of factory ground locations for your 2010.

 

I have 3 switches, all powering LED's. Some for interior, some for under the bumper, some for in the bed.
Currently inside, under the bumper both work, however the bed lights not working.
Additionally, the lights on the switches are not coming on when I turn on the dash lights? Not sure why? Did I tap in the wrong wire? Purple with grey stripe???
The connectors from HD are for 18 gauge wire and they are sold in the automotive area as well. So I thought why not, they are very easy to,use.
But I need tutorial on the multi meter now.
Do I have to pierce the wire to get a reading? Or can I just put the lead next to the wire?
Hopefully, maybe, I can get all this going and be done!
Thanks

 

For the multimeter to work, you need metal to metal contact. You can stick the probe into the end of the cut wire you added, or into the connector on the back of wherever you tapped into the dimmer circuit (dimmer switch, headlight switch, etc) If you absolutely must pierce the wire itself, I recommend taping a sewing needle to the end of your probe to make the smallest possible hole in the insulation, and fill the hole with liquid electrical tape when you're done.

 

The purple wire just doesn't work for me!
Seems like it may be the courtesy light?
It powers the LED on the switch, but when I am coming in and out of the truck!
NOT keeping the lights lit throughout?
Must be a different wire on the 2010 STX
