Auto High Beam tie-in

I just recently got some pod lights installed on the truck and wanted to tie them into the auto highbeam system. Here is my wiring digram.. I think it will work but not 100% sure. Wanted to see what others think before I try this.

 

The Auto HighBeam switch only controls the system to be ON, so tying into the switch is sort of redundant, also I see an extra relay not necessary.

 

Correct the Auto Switch is what I want to use to enable the relay connected (87 terminal) to the relay that is using the High Beam source to supply power to the lights when the high beams are automatically turned on and off when the trucks camera system detects oncoming vehicles. If the Auto Switch is turned off then the relay disengages and power is restored to the relays connected directly to the lights through 87a connector. The flow of power all starts on terminal 30 of the relay connected to the Auto switch. I have some relays coming in I plan to test all of this with a bench power supply to simulate this setup to see if it will work when the relays are engaged or disengaged.

 

Maybe this will make more sense..

This is with Auto High Beam button enabled..


This is when the high beam is turned off the 12v source to the relay is not active on port 85 so power flow to the leds is not active so lights are off..





This is with the Auto High Beam button Disabled, even with power going to the high beams since the auto button is disabled power flows through terminal 87a to the led relays...

 

No need to tie into the switch, the high beams themselves will turn your lights on and off, you don't need to tell it twice.

 

Yea but I dont want the high beams to always control the lights.. there may be times I would want them on without the high beams. The auto switch is what connects the lights to the high beams. If i want them disconnected then i can with this setup.

 

Connecting to the switch won't let you turn them on without the high beams.

You have another switch that allows you to turn them OFF without the high beams (and thus don't need the OEM switch to turn them off), but this won't let you turn them ON without the high beams due to the second relay.

Again, no reason to wire into the factory switch.

edit, sorry, just saw that one of your diagrams has a different wiring. Still, if you use the auto on high beams then you cannot force the high beams to be OFF unless you turn the lights off completely.

Personally opinion, I would just run two different relays and also two on/off/on switches. Have the switches be on, off, or on-with-HB. Then just tap the high beam itself into the side of the relay. That way you can have either or both set of lights be automatic with the high beams and can also operate both sets of lights independent of the high beams.

 

Yea so right now I have it setup with two switches.. one for each set of pods on or off.. what you said about the high beams is what I was thinking of doing but then I was thinking I may not want the pods to be on when the high beams are on and the way your saying to do it they would turn on every time the high beams would turn on. That’s why I wanted to have the relay tied to the auto button so when that’s off I can turn on the high beams without the pods turning on. The auto button works like a single throw double throw switch either power goes through terminal 87 which then sends power through the high beam relay and then that goes to the pod relays which can still be turned on or off by the push button or if the auto button is off it send power through terminal 87a and the pods can be turned on and off without the high beams being engaged or they can all be on all the time without the system trying to turn them off automatically.

 

I hadn't previously though about how aux lights could be tied to the auto high beams on our Tacoma's, but I've always run a three way switch for forward facing aux lights:

Position 1: ON
Position 2: OFF
Position 3: On with Highbeams (and I generally leave it switched here)

I pickup the trigger for highbeam from the highbeam wire at the headlight.

Whether they turn on via automatic highbeams or from the highbeam switch at the stalk shouldn't matter.

 

Yea I have the push button oem style switch for the pod light and want to keep it that way. The aux relay more or less works like that 3way switch. It would just let you choose to control them with the headlight like you said or disable it and control them separately.

 

An add-a-fuse to any of the high beam fuse would less disruptive than taping into the high beam wire at the headlight connector.

 

Sub'd for later. I like it with a caveat ...

Off road lights annoy me, and a lot of the pod lights throw their beam much farther than the high beams, so the auto-high beam might not be sensitive enough to turn them off in time for oncoming drivers.

Even the stock high beams don't turn off soon enough for my liking ... the camera / sensor is not sensitive enough for me as I really dont like being the a-hole blinding oncoming drivers. We have enough jackholes running their offroad lights in the city, or lifted shitboxes that wont re-aim their headlights.

 

I personally relocated my auto high beam to the @MESO shift knob, so I can bright through turns that are less than 30 mph (because auto high beam dims at low speed)

Here's how I'd like my light bar to work with auto high beam:
