What lights are you running? The only LEDs that I know about have two low and two high beams that are separate from one another.
 
I don’t think so, but at there very least there is some reconfiguration necessary. I’m going to rewire things so that if there headlights are on there are always 4 headlights lit, either 4 low or 4 high beams. I’ll do my best to post how the project went and how I did the rewire.

Very excited to see this write up. I NEED an update on the lights.

This is how I've got it dreamed up in my mind. I'm not much for electrical though. Anyone see any flaws in this plan? This wouldn't address the high beam indicator. I'd like to figure that out at some point, though.

Just to follow up, I did end up building according to this diagram and it worked out great. While the LEDs would have handled the 24v just fine, it just ended up being cleaner running things to my 12v fuse block that's run off of the battery balancer/converter. I used a couple of harnesses from other projects that were laying around, and everything is working great, minus the high beam indicator. If anyone knows how to deal with that on a 24v truck, i'd love to hear ideas.
 
The instructions from High Performance Lighting seem incomplete. There is no connection for the yellow wire on the low beams. This will leave the high beam filament in the low beam light unused.

Unless I'm missing something...
 
Ok, does anyone have a definitive answer for this simple plug and play upgrade?
Ie. Buy these lights, buy this harness, plug this in here and slice this to there.
No one wants to buy a bunch of pieces that don't fit together that needs returning. Or some one design a true plug and play.
And no electrician/circuitry diagrams that most don't understand. Seriously.
 
Buy one of the available wiring harnesses for your application. Buy the lights you want. Install both. Live without a high beam indicator. That’s as plug and play as it gets.
 
I'm installing Evo2 Low Beams and did the black/yellow wire swap. Using stock harness. Low beams only work when HB is ON. Anyone have this problem? Any suggestions?

I installed the JW Speaker LED's in a 24V HJ-61 per these instructions, minus the high beam relay, and they work.

They are bright enough to not need an aftermarket harness. The LED's automatically adjust voltage so the drop from the original harness isn't a hindrance. This save quite a bit of cash and makes the price of LED more palatable.
 
@tony stone What is the yellow to black wire swap? Did you build a harness as described on the first page? If you build a harness including the high beam indicator adapter with a relay, everything will work as factory.

@Juggernaught - Did you build a harness, or is your HJ61 like mine? My HJ61 is Euro spec and appears to be positive ground switched, not negative ground switched. All I had to do was make an H4 to H4656 adapter.
 
I had to swap pins around and adapt. Your HJ seems to be an anomaly.
 
LEDs require you to change the circuit from having a common power lead with a switched ground to having a common ground and switching power. In other words the stock wiring always has 12 or 24 volts on one terminal and the other two terminals will ground through the switch on the steering wheel. Vs conventional vehicles that have a terminal that always has ground and the switch controls 12/24volts.

This is all important because diodes only allow electric current to pass through in one direction. So in the stock Toyota wiring it’s as if the electric current tried to pass backwards through the LED (Light Emitting Diode).
 
Upgrading the lights on my 62 was something I meant to do and never did it. I was stuck between upgrading the wiring harness for H4s or LEDs. This time I am not going to wait...

Just got my HJ61 (24v euro spec) and I am going to upgrade to LEDs so have a couple of questions.

Cruiser Corps has a set that is supposedly plug and play - does anybody know anything about it:

Also JW Speaker has a harness for both low and high beams. Looks like it comes with the lights.

I still need to check if I am negative grounded or positive like bottom bracket. If so I am assuming I can flip the plug/ polarity and be fine?

I have heard some people only switch the low beams. Any thoughts on that? Could save some coin only buying one set, but do they work okay. Not to mention it would look kind of funny with half and half. Probably will go for both unless there is a compelling reason for just the low beams.

Cheers!

I too have a euro spec 24V HJ61. Look earlier in this thread: all I had to do was reverse the polarity of the high beams and make an H4 to H4656 adapter. Everything on mine works. You may want to do a little exploration with a multimeter before buying adapters.
