High beam fuse?

[finallyonair]

Is there a fuse under the hood of a 15 Silverado for the high beams? I'm wanting my light bar to come on with the high beams but don't want to tap into the wires at the headlights if I don't have to. I have the relays and everything to make it happen, but not sure on which fuse, if there is one.

From my understanding BCM controls the high/low and there is only one fuse for headlights. If anyone knows different please do tell

Does someone have the breakdown of the wiring for the headlights? I need to tap into high beam positive and parking light positive.

Parking light is more easily accessed through the fuse box. Use an addafuse. There's a discussion somewhere on the forum where the high beam wire is highlighted in the bcm harness under the steering wheel.

I'm trying to avoid running wires inside. I think I found that the light blue wire on the headlight harness is high beam. Now I just have to figure the parking light for the backlight of my light bars.
