I'd def be on the phone with the KC guys before you wire anything up - got this response from them re: your issue.
What worries me is that support doesn't know what the amp ratings of the Bronco are and that they're actively supporting an install video that clearly is dangerous (super hot wire...
I’m no wiring expert but it’s clear that the lights need more than the standard aux 1 wire can push, so the relay def needs to be part of the equation.
I pinged KC and got this response if it helps:

Hello Daylon,
Yes, the wiring for the Pro6 Titan will come with a relay included in it and the video below can help with how to wire it to the Bronco AUX switch...
I put Morel Ultra Integra 602s in my kicks (the ones in the floor in the front) and are happy with them.
If you're upgrading the speaker pods, make sure you have the amp to drive them - they sit at a beefy 120watt RMS - so can def take some power.
The Mobridge system replaces the existing stock DSP that's mounted on the subwoofer enclosure.
In a 4-door Bronco, you just mount the Mobridge in the same place where the stock DSP sits (replacing it), but in a 2-Door the plastic body panel is shaped differently so it can't clear the slightly...
It's a little more tricky in a 2-Door, but it can be done! The Mobridge system was designed for 4D folks in mind.
I managed to shoehorn it into the wheel well space.
I just did this over the last 2 weeks - not cheap, but the best DSP/Amp combo out there.
Paired it with some SSV 6.5'' speaker pods, Morel 6.5'' and 4'' in the front, and a JL sub.

I built this for my 2-Door Badlands based on a 4-Door design someone had posted earlier for transporting my doors to/from my parking garage (I live in a high rise, so don't have a dedicated garage space).
Basically it's some SCH40 PVC pipe, a furniture dolly, and some pool noodles. Ran about...
I've had it less than a year - '23 Badlands... I did have full aux power and everything was working - just no start ability. I'll get the battery checked just to be sure.
Post some pics if you get them!
Did you find the answer?
I just had this EXACT same problem this week. Died in the middle of an intersection, did the start/stop and it died. Tried to start again and just got one single click.
Had full power to everything, but it was acting like it had a dead battery.
Tried disconnecting...
I bought their Bronco speaker bar as part of a full B&O upgrade I'm in the middle of installing and am well impressed with it. My wakeboarding cans are like 17-18lbs each and it holds them solid no problem.
I just went the Mobridge route and did a rip / replace of everything, including stuffing an 8'' kicker CompR into the stock enclosure.
At full power (250-300 watt RMS) the 8'' overpowers that enclosure and space and I get a bad sympathetic rattle / vibration in the cone itself, so I'm looking...
Thanks for the link!
Nice boxes - but once you put the subs in and get the amp... you're several hundred bucks above that JL Stealbox - which is pricey enough as it is...
Still, good reference point.
Curious if that's enough air volume for those two powerful subs? ALso wondering if this would work as a down-firing box if you put some standoffs on the bottom.
