Not the only limitation. Disclaimer for anyone entertaining this, you will limit your whole system to 50a. Our factory setup is better than this at a total of 60a as all upfitters have their own fuses (15+15+10+10+5+5). This system has a 50a inline breaker so you are limited to 50a total from the battery despite each delay having a 30a fuse on it.

Again, in my opinion this is a downgrade. What does it really get you? If you need a relay or two, just use a relay or two.

That's a good point. And if the breaker is 50A, you probably don't want to plan on running more than 40-45A, lest you have to reset that breaker often, and there goes the convenience aspect that this is intended to achieve. I wonder if the 50A rating is a function of the cable connecting the MLC-6 to the battery or some other component of the MLC-6? Seems odd it has 5X 30A relays but you theoretically couldn't even use 2X of them at the same time if they're maxed out. If it's just the cable connection, that's easy to upgrade.

I wouldn't want to experiment lol. Looks like the relays are mounted to a circuit board. Pump more than the recommended amperage through that, especially from a Rough Country product, and you're asking to get to use your fire extinguisher.

Thanks for this thread and the inspiration on the wiring setup. I just finished setting up my Raptor with extensions over to the same fuse box, and got my lights working following your lead. Thanks!
