Headlight high-beam splice point

[AFD]

So the AUX swithces would be providing power for the lights. They can handle that? ( i haven't read the first 3 pages of this thread haha)

Factory AUX switches #1 and #2 can provide up to 40A of power each and #3 and #4 can provide up to 15A each.

@Grayhound : @THAW wiring is the simplest way to do it. If you don't have two 5-pin relays, I would buy two of those and then wire each set of lights exactly as he has shown above. Use Switch 1 &2 for the first set of lights, and switches 3 & 4 for the second set of lights. I would forget my mention of diode's altogether; his wiring truly is the most direct and simplest way to do it. You simply need two 5-pin relays and the tap from the high beam wire.

Switches 1 & 3 would be your manual on/off switch for your 2 sets of lights, and switches 2 & 4 would be your on/off switches for the high beam control (meaning they go on with the high beams when those two switches are on (which is one switch per set of lights)).

Make sense?

Ok totally the king of overthinking, but let me run one more scenario past you and @THAW

So running two relays
High beam tap is split in two and feed both relays 85

Relay 1 then could have aux 1 to 87 load to 30 and being fed by hb on 85. 87a feed by aux 3 (manual switch)

Relay 2 aux 2 to 87 load to 30 one of the split hb tap to 85 . 87a feed by aux 3

So my thinking is when I have aux 1 on I would also need either aux 3 or high beam to work

I could also have aux 2 with same feed for hb or aux 3 to power.

In this set up I could still control each set of lights with aux 1 or 2 or both with either high brand or manual.

Does this sound right?

Is your goal to have only one "manual" switch to turn on both sets of lights?

Yes essentially I’d like the manual switch to work just like the high beam trigger. It can work in tandem to light up either or both sets depending on which other aux switch I have on.

Yep, decent way to save an aux switch for a different purpose. But you have to engage the high beams to individually control the aux lights.

Split the "manual" aux switch power wire and run it to the 87A pins of both relays (as I believe you indicated). Make sure the "manual" aux switch fuse is rated to carry the load of both aux lights combined.

The button pressing to light function matrix does potentially become more confusing, though. And there's a minor functional difference. If you use the "manual" switch and only want one set of aux lights on (done by turning ON the aux switch connected to the aux lights you want OFF), engaging the high beams will switch to the other set of aux lights.

That is an interesting side effect that might look really cool in light show!

Appreciate all the help and expertise!

I confused myself and made some misstatements which I've corrected in the original post.

I think this circuit diagram may show what you actually want using a shared "manual" switch:

Or at least half of it. You'll need 4 relays total. Connect the "manual" switch and the high beam splice to the 85s of the other 2 (not pictured) relays for the second set of aux lights.

Note the "manual" switch doesn't turn on any lights by itself.

I was thinking the manual switch would be shared by my winch switch and I could come off the solenoid.

Yes yes yes this is exactly what I’m thinking I believe! I’ll study it some more to make sure I can imagine it with the physical parts

You guys lost me. 4 relays? I belive it’s wired correctly…. But I need a pencil and paper to understand why. All good.

I diagramed it as a test just for you ?

@THAW @bobholthaus

I followed the schematic used 4 relays and have the high beams triggering my aux lights with a manual override on my winch switch!

Again I appreciate all the help!

Hey, I know this is slightly dated, but did anyone find an alternative for a pigtail to be able to do a direct plug and play into the headlight high beam? I really don’t want to splice into my wiring harness…. I found the site @Stewtomcat mentione (thanks!) but they are back ordered and want $60 shipping!!! (I don’t mind the $40 for the pigtail to avoid the splice….. Hoping somebody has a different option - their site for reference:

I spent some time looking as well, and the Stedi UK harness adapter was the only one I found.

Probably not a big deal using a Posi-Tap, but I'd rather spend $40 and buy a pass-through versus risking corrosion potentially messing up my factory harness and LED headlamps if the splice (or Posi-Tap) isn't 100% waterproofed just right, especially in that location. The extra $60 for S&H is insane, though.

Would be a good project for @Baja Designs , @KC HiLiTES or @Diode Dynamics for their JL & JT customers that would like a safe/simple and easily reversible plug-and-play solution to control their off-road lighting via highbeam.
