    I just went out and started my truck. when I turn the fog lights on with it running in park and the headlight switch in auto it turns the fog and running lights on. I can understand having a diode in the right direction so the fogs come on with the running lights because if it's backwards the fogs would not come on with the headlights or park lights. maybe the diode is redundant. would require some testing.

    Diode makes sense to power the fogs when parking lamps are on. If you don’t have parking lamps on during the day and you turn the fogs on then you will power the parking lamps.


    Technically wouldn’t you need a Y made with diodes to be powered with DRL during the day and parking lamps at night? I haven’t checked if the fogs come on during the day yet. I know they do during remote start but haven’t seen with the key on.

    Took it to get inspected. Plate renewal is due at end of month. Hard to believe I've owned it 2 years

    that freeway is terrible, has a lot of things going bad with it, rolling small hills, slight turns, no room to even pull over and stop, each side has a large ditch, some of the ditches are filled with water, it has 3 bridges that close at random times for boats to pass thru resulting in unexpected stops, HEAVY traffic, only a couple passing lanes.
    so if you have to emergency stop your choices are limited, eat a big ditch and maybe flip over, end up in the water-possibly upside down, enter the opposing lane, crash into whoever.

    $20 for wire taps and a diode....lol

    Don't quite understand how this is different than how I've done it, except it's at the BCM under the dash and not in the fuse box.

    Boost Auto Parts even stated in the comments of one of the videos that the fog lights can't be turned off after doing this mod, so don't quite understand the purpose of the diode?

    It’s cleaner because it’s not in the fuse box with a wire in plain sight. And you can’t toggle the fogs off just like you can’t toggle them off with the fuse box jumper. If your park lights or headlights are on, your fogs are on. The only way you could toggle them off is to hook the switch to your jumper wire but we want to be able to toggle the fogs ON without park or headlights thus the diode.

    Looking at different tail lights. You guys think these go with the U bar style head lights I have? Seems like a lot of red when brakes or signal is on. Also thinking about maybe the 15+ style Yukon tails

    Or maybe the smoked ones....

    I think they look good, they’re just like the ones I put on my Silverado and I found a matching 3rd brake light.
