Video Transcript for Review of Blue Ox Tow Bar Wiring - Bypasses Jeep Vehicle Wiring - BLU79FR

Hey everybody, I'm Ellen here at etrailer.com, and we're going to take a quick look at the Blue Ox tow bar wiring kit. This is going to be a basic kit to get that wiring function for flat towing your vehicle behind your RV. It allows you to transfer the lighting signal from your RV, into your vehicle. So, you'll have your running lights, tail lights, and your brake light signal going into your towed vehicle, so the drivers can see what's going on whenever you're making those signals, and it's going to keep you safe and compliant, while you're out on the road, flat towing with your vehicle. The nice thing about this kit, is that it is custom fit, so you're not changing anything about your vehicle's wiring. You're not cutting or splicing into anything.

This is just going to work with factory plugs, plug and play application. Should be pretty straightforward to get installed.You also don't have to worry about putting in individual diodes, which can be really cumbersome for other permit mount kits. That's something that I really like about this as well, is that it's pretty easy to get installed, and should make a great addition to your flat tow set up. So, let's take a little closer look, and talk about what this fits. So, we have our diodes here.

This is the brains of the operation. This is going to be what separates our vehicle, or isolates it from our RV's wiring. We don't have to worry about any back feed going from one end to other. We'll have our four-pole connection to go at the front of our vehicle. Now this, you might need to end up cutting off.

This is a basic wiring function, or a basic wire set up. Some RVs will still use the four-pole, but a lot have moved on to a seven pole.So, what you'll do is cut off this end, save the white wire, and then plug it up, or wire it into a seven pole plug, or whatever matches your RV. It might be something else like a six pole, or a five pole. You can find all kinds of accessories, and different plugs here at etrailer.com, if you need to go that route. Should be a good length of wire to go for your vehicle.

We'll have our two wiring plugs that are going to just run right in line with our taillight wiring. One goes on the driver's side, the other one goes on the passenger side and this kit is a custom fit for the 2020 through the current Jeep Gladiator, and the 2018, through the current Jeep Wrangler. That's with, or without the tow package, so it's just going to match right in line with those plugs, and plug right in.We do get some hardware to go with this. We'll have some zip ties, we can cinch up all our wires, make sure that there's nothing hanging down. Everything's anchored off nice and neat. We want to make sure any wire that's going to be going underneath the vehicle, you keep it away from anything hot, like your exhaust, or anything moving, like your suspension, and anchored off in several places, so there's no excess dragging. We'll get some dielectric grease, always a good idea to put those that on any of your connectors. Just needs a little dab, and we'll also get a dust cap and a bracket for that four-pole, if you do end up using it, and also some mounting hardware for that bracket. So, that's pretty much all that comes in the kit. It is made in the USA, and that's pretty much all we have to look at with this video.I hope this has been helpful in deciding if this is the right part for you. As well, you want to look at our website here at etrailer.com for any other accessories for your flat tow set up, since this is just one of the main components for a complete flat tow setup. You'll also want to get your tow bar, base plate, and your safety chains, if you don't already have them included with the tow bar, and also a supplemental braking system. You can find all of those accessories and more right here at etrailer.com, along with a lot of other content, to make sure that you can get it installed, and get everything right the first time. So, check it out. Thanks for watching.

Not a happy camper…. I was sent the wrong part. Then I was asked by customer support to send pictures and descriptions of what was received in order to get a refund. I got only a partial refund because I was charged for the shipping. I have also emailed the customer service (Danielle) 2 times with no reply.

First off let me say this is not my first order from etrailer. Previous orders have been very smooth with timely delivery and quality product with excellent customer service from available Technicians to help out with issues pertaining to installation. This current order arrived with the major component missing (baseplate). etrailer has stepped up and is currently doing battle with UPS. Thanks to Nicole R. for all of your attention to this matter. I will continue to do business with this upstanding company in the future. Merry Christmas!

  • Recommended Tow Bar Wiring Harness For 1997 Jeep TJ
    Thanks for the pictures! The Blue Ox Tow Bar Wiring Kit # BLU79FR you were looking at has square connectors that will not plug into the connectors you have on your 1997 Jeep TJ. Since we do not offer a custom wiring kit that will plug into the connectors you have on your Jeep, I recommend the Roadmaster Universal Hy-Power Diode Wiring Kit # RM-154 which will splice into your factory harness and the included diodes will protect your factory wiring from feedback or damage from your tow...

Since this is a diode kit that means it installs by splicing into the taillight circuits and comes with a coiled adapter to go from the front of your vehicle to the rear of the motorhome. Like most vehicles there isn't a kit that would be plug and play. We had the chance to install this on a similar 2021 Gladiator though which I attached...
