I believe I may have originally told you wrong as I installed the tonneau and running boards at the same time. The tonneau does come with a small parts box. The running boards however use the (M8 I believe) bolts that are already screwed into the truck.
If you want to go by 99% of the rest of the world (metric), you would be wrong. 1.5 metric tons (tonnes) = 3306.9 pounds.
1.5 short tons (Imperial) does = 3000 pounds however.
So technically you're both right. But Metric makes thinks so much easier.
Yep, this is posted on here a few times.
It's due to the fuse that you wired it in to. I believe it's IGN? IIRC.
It does a self test every so often and powers up, which is what you're seeing.
OEM fog lights should be a standard H11 connector. If the Rigids are Deutsch connectors, it should come with the H11 to Deutsch connector. If not they're easy enough to source.
I don't think your stock light bar is attached to CANBUS. I could be wrong on that, but you just have a switch for it, and that switch is probably tied to the high beam signal somewhere along the line.
Regardless of how it's wired up, simply wiring a new light bar to Aux1 wouldn't mess anything...
