2014+ Jeep Cherokee Trailer Wire Harness Install | OEM Mopar

[@randylang8344]

By far the best in depth tutorial on this. I’ve only seen universal ones and not oem but wow excellent job man!

[@RatchetWrenches]

Thank you! We try to make it as easy as possible for everyone to follow along and save yourself some money by doing it yourself!

[@Velo1010]

I totally agree!

[@alejandroromo1536]

You didn't have to drill a hole that black cover comes off and that's where you feed your wires through and where the grommet goes

[@Velo1010]

By far the BEST tow hitch wiring installation video on KZbin. Thanks for making and sharing.

[@RatchetWrenches]

Velo1010 thank you! We try to make it as simplistic and easy to understand!

[@saintATM]

If you don't want to pop any of your plastic pieces off, you can also run the power wire from the battery under the car along the brake line avoiding the exhaust.

[@robesaiw402]

i have the exact vehicle so these are extremely helpful....... hey from Vancouver Island !

[@sikkonee]

Thanks man appreciate the hitch and electronics tutorials

[@RatchetWrenches]

You’re welcome! Glad you found this helpful and thanks for watching 👍🏽

[@ihcterra4625]

When using a hole saw on metal, take the saw of the arbor and just use the pilot bit to get started. That way, when you pop through with the pilot, the saw doesn't slam into the surface at full speed and bend the pilot. Then put the saw back on and put the drill on slow. Leaving it on high will heat up the metal and may even harden it. Your hole saw and pilot will last a lot longer and it will be easier to drill clean holes.

Nice tutorial!

[@husker_nation]

Thank you for this tutorial!

[@RatchetWrenches]

You're welcome!

[@David-xk8hb]

Great tutorial! Is there a part (cover or dummy plug) to cover the hole where the wire harness would go if want to just install the MOPAR hitch receiver and bezel (say for a hitch bike rack), but leave the wire harness install for a later time?

[@anthonysheard7408]

Good video. Thank you.

[@RatchetWrenches]

Thank you, thanks for watching!

[@TheJImbolay]

ther are two holes in the same spot can you use them?

[@Marine-72]

Very impressive, thanks!

[@RatchetWrenches]

Thank you and no problem!

[@johnviera3884]

Good luck installing the Mopar hitch yourself you have to remove the rear bumper and fenders. Thanks Mopar.

[@RatchetWrenches]

Yeah they definitely don’t make it easy that’s for sure!

[@mnothem1]

Thanks! Hey can you check if this same kit works on 2021 and what differences there will be?

[@petekane2501]

Wow very complete project review . A lot of work you did a great job. What would you expect- to charge someone for this job?

[@markstewart4199]

Awesome work/video. Super helpful! Any idea what the towing capacity is on this trailhawk now? Does it get the around 4,000 lbs because the trailhawk has the same components as the "tow package"? (engine cooler, transmission cooler, same size breaks) Am I missing anything here? can't seem to find a credible answer.

[@RatchetWrenches]

Thank you! The towing for this Trailhawk is around 2500 pounds max

[@brianbrown9877]

This is what I found: 2000 standard 4500 with 3.2 liter. fourwheeltrends.com/can-you-tow-with-a-2019-jeep-cherokee/

[@orbelgalvarado]

3.2 V6 TH - 4500 lbs 2.0 I4 TH - 4000lbs Per manual

[@masoncamp5871]

@@orbelgalvarado I think the tigershark engine is only 2000-2500lbs

[@bernswonger57]

From what I found out, other than the things you e mentioned, the larger V -6 enginel. Then you will be able to tow 4000 lbs with a 400 lb tongue weight. Other wise it 200- 2000. What I could never understand, none of the added equipment delt with beefing up the suspension, so how do you get an additional 200lbs tongue weight?

[@freddyj5845]

Sadly didn’t work for me. My rear lights don’t work now. Will be taking it to the dealership and get it fixed

[@johnkerr6685]

Will this work on the 2019 Jeep Cherokee Trailhawk Elite?

[@rayalexander2933]

Is this a 7 pin installation and will it control breaks on the trailer being pulled or just the lights? Great video! Thank you!

[@RatchetWrenches]

Yes a 7 pin and it will control everything! (Brake lights, turn signals and any other light on a trailer) thanks for the comment!

[@johnviera3884]

My Grand Cherokee has a factory harness under the back bumper. You just need to plug in the appropriate harness connection for your trailer and then use AlfaOBD to activate the factory harness.

[@paul-stephendouglas5252]

I'm having the same issue. What steps did you take to flash your lights?

[@johnviera3884]

@@paul-stephendouglas5252 look up this Alpha OBD software. you need a special OBD connector that plugs in under the dashboard. The software is like $40 and the OBD connector is like $15. I found it works better with an android tablet. Then you need to use the software to activate the trailer lights option. or you can go to the dealer and pay them to do it. They wanted $250 for mine. But the AlphaOBD software is great for any other issues you might have in the future. It’s a way to hack into the computer without having to pay the dealer. There is a bunch of Alpha OBD tutorial videos on KZbin. my friend just borrowed my android tablet and OBD connector to fix the air ride suspension on his 2017 Dodge ram pick up truck. 👍🏽

[@commanderfox4387]

the blue wire on the harness at 8:27. Did you connect that to anything?

[@Kez77]

My Mopar setup was installed by the dealer at purchase (4 years ago) & I’ve only just realised the reverse wire/pin in the trailer socket doesn’t have any power to it. After watching this, I’m guessing it’s not something I can fix myself :(

[@terrellhaygood3605]

[@bigpoints101]

How do you tune or activate your break controller for the 7 pin?

[@RatchetWrenches]

Unfortunately you’ll have to take it to the dealer 😬

[@garylucas6511]

You can tell you have done this before and know what you are doing!

[@RatchetWrenches]

Thank you!

[@Minicprlvr]

Appreciate the video. In the wire going to module, there's 1 blue wire that says to "go to the brake controller". Did you skip that step and not have a brake controller installed? Or what did you do with it?

[@Boxboywrx]

The "brake controller" is an optional addition that would have to be purchased separately and is only needed if your trailer has its own brakes. so if you do not have a break controller the blue wire will not be connected.

[@thomaskopler4384]

How many hours does it take to install?

[@RatchetWrenches]

Really depends on your mechanical capability and if you have all the tools, but it’s say around 2-3 hours

[@AnythingAuto]

The grand cherokee 2018 plus requires the computer to be programmed before its active. Does the 2020 cherokee need programmed or did your lights and brake controller work

[@RatchetWrenches]

This was installed on a 2016 Cherokee Trailhawk and we did not need to reprogram anything. I would not doubt a reprogram would be needed on the 2020 since it is a newer model but I am not sure I would conduct some research online first.

[@RaymondAbrams]

Where does the blue wire go?

[@Boxboywrx]

The blue wire is for the "brake controller", which is an optional addition that would have to be purchased separately and is only needed if your trailer has its own brakes. so if you do not have a break controller the blue wire will not be connected.

[@rarelibra]

you said 41mm... there is no such thing ... a 1-1/2" circular is 38mm, and a 1-3/4" circular is 44mm... but even using the 1-3/4" circular, how the heck did you fit the 7-pin plug through the hole? It was not possible. Better to feed the harness FROM BELOW as you only need to feed smaller lines and then fit the rubber plug on nice and tight.

[@RatchetWrenches]

Good to know

[@akeaton14]

Bro I thought I was the only one that thought this till I found your comment. That 7 pin is like 50+ mm wide no way it's going through that hole. Currently feeding the wire through the bottom like you suggested

[@rarelibra]

@@akeaton14 great to hear it helped someone! It's a great addition to the Cherokee

[@m.w.h.9253]

I'm reading comments about to ask him where he got his 41mm circular. I've been looking all over and can't find one.

[@rarelibra]

@@m.w.h.9253 you won't. Just feed from the bottom and be done with it. Too easy.

[@wesleyhedden4784]

So you having to add the hitch and wire harness what is your max weight you can pour then? Because it’s not the original tow package

[@RatchetWrenches]

I cannot find a definitive answer unfortunately but I believe it's either 4,000 or 5,000 lbs based on this one website I'm looking at

[@m.w.h.9253]

I have a 2015 Cherokee trailhawk and put the Mopar hitch receiver on. But have been somewhat confused on how much it'll tow. I've seen 2000lbs and then 4500lbs with a tow package. I even called a dealership and he was unsure. He was saying the same thing I looked up online. That's a 2500 difference. I don't want to try to pull 3500lbs if it's only 2k. That's a big risk.

[@johnwinter5947]

Cool 👍

[@RatchetWrenches]

Thank you!

[@jatwell22222222]

Great video! I have power at the 7 way but no turn signals. Tried a trailer and no luck. It is mopar, but dealer installed. Any suggestions on why only power and no turn signals?

[@RatchetWrenches]

Thank you! And hmm that’s interesting. It’s definitely something with a connection issue. But if it was installed by the dealer I’d take it back to them! They sh out of fix that for free

[@masoncamp5871]

Spoke to Jeep Dealer Yesterday, they said the cable had to be tied into some kind of module under the hood. And needed to be programmed to recognize the wires and make the lights and everything work from the back to the front.. Cost just for the programming was going to be $170 even though I said I was able to wire everything up to under the hood.. (taking the knowledge from your video and a couple others.) Said also that even if I was to go get the U-Haul hitch and wiring installed that I would still need to come to the dealer in order for their work to be completed.. Anyone know anything about this?

[@baroquebeatz]

Sounds like bullshit. Aftermarket doesn’t need any dealer programming.

[@wesleyhedden4784]

Where did you buy your harness from? Website?

[@RatchetWrenches]

It’s linked in the description

[@freddyj5845]

Would this apply to 2020 Trailhawk?

[@RatchetWrenches]

It might be similar but I can’t truly say idk how the layout is on the 2020 unfortunately

[@texaswoodwrx]

Harness is different for a 19, a lot more connections, ignition connections, ( you have to punch into the wire box)a blue wire (have not a clue what it's for) directions don't mention it. They show you pictures, nothing is explained. This video doesn't help with a 19 TH
