Ok, so i went to get a few things i needed for the install. I asked about the add a circuit and the guy gave me a box of spade terminals and said they will work. Also, what gauge wire should I use? I got 18 guage, is that ok?

 

an add a circuit has a fuse...a spade does not. Two completely different things.

one wire is fine. looking at the KC install PDF, the ground from the KC switch did not return to the relay. (The PIAAs had the switch ground wired back to the relay to ground there.)
Just ground the OEM switch with the ring terminal attached. Same difference.

Look at the OEM switch diagram thread link. It spells out the Gauges. I think I used 18 on all the switch things.

I would go to a different autoparts store and get an add-a-circuit. You could used the white KC wire with the in-line fuse with the spade connecter if you want. I would use the add-a-circuit because then your fuse is right there at the fuse panel. Easy to access and replace if ever needed.

 

Just to update..I did the install...it was slightlynpainful but in the end it works great...thanks for all the help..I didn't get pics during the install but I will post the end result soon..thanks for all your help bc..

 

No problem. Glad you got it installed and working!

That's the great thing about this site...lots of helpful folks! I'm happy to contribute when I can.

 

I applaud your efforts in helping others. We really appreciate it.:clap:

 

I'm sorry to ask this question it seems the more I look into the install the more confused I get. I had a quick conversation with the folks at metaltech they have seen installs where the oem switch and harness is plugged according to stock instructions and no extra wires need to be brought from under the hood to the cabin thru the firewall.

 

You can do this...

If you follow the instructions, the white plug has a place to plug into that connects to a loose plug in the engine bay. The engine bay is a 2 wire plug.

I need to get some t taps and will be finished with my install tomorrow.

 

Well that would have made things easier. I made a very small hole in the boot for the firewall. I am not sure if you can do that, but that would be great if it can.

 

K since my previous scheme seems to be virtually impossible can someone help me confirm this is the right way to connect the PIAA wiring to the OEM AUX Switch? Specially the wires from the PIAA relay to the switch!

yes....exactly.:bigthumb:...EXCEPT pin 4 is out to relay. See above for pins layout and here-http://www.fjcruiserforums.com/forums/how-technical-articles/49978-oem-aux-light-switch-diagram-schematic.html

OOOPPPPS Sorry I messed up the wire order when I created the diagram...

This should be correct now right?

 

Great graphic! I should have done that earlier. You look like you're good to go!

 

AWESOME... Great news! I will let you everyone know how it goes, thanks a million for all your help

 

Forgive my ignorance, but could someone please explain the significance of the button/loom in this photo? I understand it is a non-returnable item from TRDParts4U due to a modification. I suppose my question is what does this button/loom do differently than factory button and factory switch?

 

Nothing...that IS the factory switch and harness in the photo. (exactly how it comes from Toyota.)


To do the install with aftermarket lights, you will have to cut off the white plug....then it is non-returnable.

 

Thanks!

I knew it was the factory switch and harness, but figured it wasn't returnable due to a mod that TRDparts may have done due to demand.

 

This all worked really well for me. The only part that didn't work is that the LED does not light up when the switch is engaged? The words illuminate, so I assume I wired the back-lighting part of the circuit ok but no LED. I thought it would come on with the switched +12v wire but never did illuminate. Re-capping, My fog lights work via the switch, the back-lighting works, just no LED. Anyone got any Ideas? Is that part of the switch bad?

Thanks in advance,
Eric

 

Are you using factory switch. Not sure what you mean by words illuminate but led doesn't. I had trouble getting the switch to light up when the parking lights were turned on. I had to play with getting the t taps to make a connection .

 

I'm sorry I should have been more clear, I was typing in a frustrated hurry between finishing the project and going out to dinner with my wife. Anyhow, I did use the factory AUX switch. What I meant about the words illuminating is, when you turn the lights on and the dimming circuit kicks in all the buttons that have words i.e. "RR DIFF LOCK" illuminate. Just the LED doesn't work.

The other thing I neglected to mention is that I got some wires crossed early on and I burned up some component that was inline with the green wire on pin 4. It looked like it may have been A diode or something like that. Does anyone know, if by not having that component inline with the switched 12VDC wire on pin 4 i'm doing some damage to the parts, or if I may cause some harm to myself or my FJ?

Thanks A Lot,
Eric

 

Are the lights for the switches tapped into the dimmer circuit? I need to add a gauge with lights and need to know the easiest way to tap into the dimmer line.

 

Have you thought about an independent 12v dimmer?

 

:boohoo:PIAA 520 series fog/drive set...question? Is 85w too much to draw???Anyone :habbobuggs:help educate my lame self? ----Lame in Las Vegas

 

No, they only draw 7 amps.

 

im looking to mount piaa 510s behind the lower grille. i wanted to know if its easier to put the switch in the middle console area or on the left side next to the steering wheel. Idk if maybe one way is easier than the other running the wires and such

 

Left of the steering wheel is probably the easiest but the console isn't hard. I have put switches in both.

 

I think the center console is really easy. I went through the trouble of taking everything apart to get to the center console. You really only need to remove the panel that holds the radio. I was able to get to everything by just removing that piece.

 

Anybody know any reason why, if everything else works, i.e. fog lights turn on/off, dimmer illumination works, the LED within the factory AUX switch doesn't?

 

Do you have a good ground? I would check that first.

 

Hey guys, here's a good one for you...
I installed new foglights yesterday, abiding by the factory installation instructions and using the OEM switch. I got it wired up, T-tapped into the A-trac illumination wires and plugged the white plug into the corresponding location behind the driver side kick-plate and properly grounded it. I then cut the plug off for the foglights in the engine bay and wired my foglights in accordingly and installed the relay and 15A fuse in the fuse box. I went to test them and the only work with the high beams?! Is something crossed? I cant imagine this is how they are supposed to function. My 4Runner worked just the opposite way, i.e. low beam w/ fogs.

Can someone help me?

 

If you used the OEM harness and followed the OEM instructions, then you did everything correctly.

That is how it was designed. There are posts about how to modify it to have it work not with high beams.

 

This thread is confusing to say the least. At the end of the day, if you follow Toyotas instruction manual for a "clean" install. You can only use the new fog lights with high beams.

This sucks donkey dic*.

 

i have done this install, my issue is now my high beams are on all the time any suggestions on what went wrong????

thanks in advance
