Curt Plug-and-Play No-Splice Trailer Wiring Harness Out For Bronco

[ManBearPig]

I was fortunate enough to come in on the tail end of this and have the Halogen kit 56471 in front of me. I should not have to re-pin or float any grounds. At least I dont think.

I have studied the instructions and they make no mention of running 12v power to thic onverter box. The box has an unlabeled black wire...I assume this needs 12v?

Really would prefer not to run a wire to the battery just for this. Is that still neccesary on the Halogen specific kit?

I bought a male end of a 12v plug and just tuck it underneath the rear cargo are. When I want to use the trailer lights, I just plug it in. I didn’t want them

I read the instructions multiple times without seeing the mention of connecting black to the battery. Read it one more time and found it in the images of the wiring not the written content.

I went ahead and ran the wire from battery down the underside of the frame to the module at the back end. I may at a later time install the diode kit to make the tail lights work in concert with my RV which also requires 3 wires front to back. I installed the black wire for the module and the 3 wires for the diodes and just left the 3 wires unconnected at this time. I can always connect for the diode kit or leave unused if I don't go that route. Wasn't hard just time consuming.

I enclosed all wires in split plastic loom to protect from rubbing and creating electrical issues later on. For the life of me I cannot understand all of those who run wires like this along the frame and don't protect in some type of wire loom. Even the E-Trailer videos don't show them doing it. Doesn't make sense to me but that was the most time consuming part of the install. It also looks more professional and like I knew what I was doing.

I also have the Curt trailer wiring kit. I am thinking about wiring it up to use as a 'towed' light set up but am having a mental block on were to put diodes, can you provide an explanation or diagram. I already have the 4 wire from the front to rear of the Bronco for the auxiliary lights I have installed.

I could also daisy chain the Curt towed harness in but afraid there might not be room for mor plugs behind the taillights.

I ran the 12V wire from my battery to the module on my 2006 Escape and it still works today. Unless it is rubbing on something, it should be perfectly fine.

Pretty much above my skill set what you are asking. I pretty much search in this forum or ask questions and go by who I think knows what I am trying to do.

Search threads by member grtharris, I've read some of his posts and he seems to really know what he is doing. He did the diode install and if you find it I'm pretty sure it will help. I think he had the factory hitch and wiring install but the diodes I think will go in prior to the Curt hitch wiring we both used. He has been very good at answering my questions as well so a pretty helpful guy in the forum.

Any reason not to ground to the bolt circled in blue here? Behind the taillight

For the record: I used this bolt as my ground and had issues with rapid flashing turn-signals. The bolt appears to have a galvanized protective coating on it. Using a razor I scraped the coating off the bolt/washer and the issue appears to be fixed.

I think this is what I was trying to convey. Ford told us at the beginning that Bronco would be modular. What they didn't tell us is that anything that wasn't ordered from factory wouldn't include connection items. dropping tow loses all wiring. Soft top loses all hard top connections. Modular bumper gets no fog wiring. I knew "eventually" the aftermarket would catch up with many things but I really had no idea when I put down that reservation deposit day one that these things would be pouring out before I had mine in the garage. Then again I ordered a Badlands thinking it would be the most likely to have options only to find out that the aftermarket does not include Badlands in 90 percent of their offerings.

Just to demonstrate 'weird Ford Rules' I added the Modular bumper to my 23 Wildtrak, so I lost the fog lights in the capable bumper, but they did include all the wiring for the fog lights in the Modular bumper.

weird, I'm using this bolt without issues.

I posted this in another thread, but it might be relative here if you're going to use both Curt tow and towed wire harnesses.

I have towed my Bronco for over a year now, all good. I currently use a set of strap on lights which I built and work fine, but I'd like a cleaner set up. I have a Curt hitch and trailer wiring, which after modification works fine too.

I'm considering adding the Curt towed wiring. Does anyone know if this can be daisy chained with the Curt trailer tow harness? Will there be room behind the taillight for all the connectors (it's been awhile I can't remember)? I assume I would plug it in farthest upstream, between the Curt trailer wiring and the factory harness, correct?

new post:

So I daisy chained Curt towed/tow lights, everything fits, barely, and works.

NOTE TO THOSE PLAANNING TO USE CURT TOWED AND CURT TOW WIRING: the towed harness now comes with an auxiliary plug to hook up tow lights. So, you can get towed kit 58996 and tow 58920 and not have to fit 4 plugs behind the taillights..

I installed the Curt plug harness over the weekend - took a couple hours but relatively painless.

Those plastic screw/clip things holding the trim panels on next to the lights are pretty lame though - I had to drill two of them out. Anyone have a PN for these or have an Amazon link to replace them?

Do the brake lights still work if we cut the red wire when installing this on base bronco?

I had already purchased the other model when this new one wasn't out yet, so I'm about to install it now that I received my bronco
