Ok, so this is for anyone who has a 14-15 truck that still wants to do the OEM headlight switch with the Off-road button. Or if you want on/off without delay for the 16-18. I found that the Amazon latching relays were unreliable in functionality. This way works perfectly every time. I'm not a 100% sure but for the folks that have a 16-18 truck you might be able to run the grey wire to bcm and to the relays and still get the dash icon light to come on. I will test this when I wire up my 18 in the future.  

Hey bro so I tried the relay setup and CAN'T get it to work don't know what i am doing wrong... Om the relay diagram you have the yello wire connected to 12v output there is no power. And on the wire where the gray wire connects to relay it has power always. I checked my connections with the diagram. So not sure what the issue. Can you help?

Did you hook to the bcm at all? If so it could be causing the issue. Can you send me some pictures of the wiring on the relays?

The 14-15 trucks don't have the bcm programming for the dash indicator. And you will have to make a latching relay like I made here in this post. And not hook wires to the bcm.

Yes in the picture the yellow wire goes from switch to tie in between the relays and the light bar. Everything in the diagram picture is as it should go.

You can try connecting the gray wire to BCM amd see if it will light up the indicator light on the dash. GRAY WIRE TO PIN # 12 WHITE BCM CONNECTOR. Let us know if it works plz.
