My buddy is running them and swears by their performance. He told me there are several circuits inside them and have a lot of options like high/low beam and running lights. I have no idea how he has his wired but I can't imagine it's very complicated.
I went with a lower cost option as well (not Harbor Freight). I figured for the little I'd really need them, they'd be fine and I can replace them 5-6 times over vs. the cost of some other options.
I bought a pair of the Edge 4s this week on HF's big sale and I'm curious about how any auxiliary switch Bronco owners wired these as well. According to AI, I should wire both highs to the 30A switch, both lows to the 15A, and the backlights to one of the 10A switches. Seems like the logical way to go. But there's more than one way to skin this cat.
After doing a bit more research (and in an effort to minimize the wiring requirements beneath the hood), I've decided to wire the Edge 4s as follows:
- High beams - 30A switch 1
- Left low beam - 10A switch 3
- Right low beam - 10A switch 4
- Amber backlights - 10A switch 6
What I like about this method is that there's no risk of overloading any one of the switch circuits and there's a nice separation between the 3 functions on the switch panel (supposedly, triggering the highs and lows simultaneously causes them to burn out).
The only downside is that I'm using up 4 of my available 6 switches. But I don't plan on wiring up anything else anytime soon and I still have the 15A and one of the 10A switches unused.
Now, I just need some time to actually execute this plan...lol.
If you don't want to overload a circuit simply use the overhead switch to power a relay that can then send any amount of current up to your batteries max output.
I went with the 4-switch setup instead for 3 reasons:
1. I really have no use (yet) for the other switches, so I used up 4, to safely distribute the load. Switch 1 for the high beams, switches 3 & 4 for the left and right low/flood lights, and switch 6 for the backlights.
2. I tried as hard as possible to not mess with the battery, even going as far as removing the switch fuses instead of disconnecting the battery. I don't like how much it disrupts the systems in the cab (windows, resetting everything, etc.).
3. I like having the options and flexibility of turning on each function with a dedicated switch. And I like having the left and right flood beams separated in case I need to light up just the left or right side of the Bronco.
Just made the most sense for my needs. But there are definitely so many ways to go about it.
