Wiring led lightbar to high beams AND aux switch

[2015sierrablack]

Getting ready to install my 32" curved led light behind me grille in my 15 Sierra at. I'm looking for an explanation on how to wire the light to come on when the high beams come on or when I switch them on with my wireless remote harness (that I'll be programming into one of the garage buttons). I was going to get the high beam signal from the brown connecter behind the ecm.

 

I have the wireless harness and an extra relay if needed. If anyone with an explanation on how to do this or a link to where someone has alrdy explained this that would be sweet.

So the factory lightbar activation is wireless? If so, you would have to either find a way to activate the factory wireless relay from a switch, or add in a second relay to bypass the factory relay.

 

Personally, I've never heard of wireless remotes working well for this. I know Warn uses them, and I've read of plenty of them failing. I would hard-wire everything using a 3-way switch and a single relay. The 3-way switch (on-off-on) will have one lead coming from the high beams, and one lead coming from the a switched power source (ignition). In the Auto position, the lightbar would come on with the high beams, in the middle, off position, the light would stay off, and in the On position, the light would be on constantly with a switched power. I did this on my previous vehicle with fogs and reverse lights, and it was amazing. I would also use diodes between the switch and power leads so there's no back-feeding of signals to the canbus.

Okay that makes sense and ya I got diodes left over from the dogs on with high beams mod maybe I'll go that route instead of wireless, just wanted to avoid drilling holes in these overpriced machines lol. Thanks for the input Mack

Thank you a lot for such a great thread here! I am new to this forum, and I have a very similar question. I've recently got an LED Ligh bar for my truck from Ledoutfitters store, and I need some guidance for proper installation, wiring, etc. I will appreciate any help as I am not good at such things at all...
