Jeep Wrangler 6.4 Hemi Swap Wiring and ECM

Full Parts List: docs.google.com/spreadsheets/...
Back in the garage working on the 6.4 SRT Hemi V8 swap for my Jeep Wrangler!
In the last video, we removed the old 3.8 factory engine and dropped the 392 in place.
Not only am i upgrading to the 6.4 Hemi, but i am also running the 8 speed 8HP70 auto trans behind it. This is possible by using the Jeep Speed Shop kit! Jeep speed shop makes a ton of DIY parts that will allow you to do this Jeep Wrangler V8 swap at home in your garage.
So far, everything is fairly easy and straight forward. I strongly believe that anyone with some basic mechanical knowledge can do this swap (Along with some help from my videos).
I didnt mention it in the video, but Jeep speed shop will offer 10% off your order if you call in and mention that you were watching the JK Gear and Gadgets videos. I am not sponsored by them... and i paid fully for these parts, but i was able to get a discount code for you guys! (Thanks Ben!!...)
I am using their Hemi Wiring Harness, ECM, 8 speed trans mount, 8 speed kit, steering relocation, Camaro fan shroud and controller, and eventually their AC lines.
The JSS website can be hard to navigate, and reaching them on the phone can be hard. It is a small shop consisting of 3 people, however the kits and parts they make are outstanding, so be patient.
Info on parts years and models:
8 speed trans: 13-17 Ram 1500 4x4 w/5.7. this is a 8HP70
Shifter: 15-18 Challenger with any engine
Truck VVT 5.7- 09-20 ram 1500

Transfer case with 8 speed- 07-11 Auto, 07-19 Manual
Camaro Fan- 16-21 Camaro, CTSV, ATS
Parts:

In the next video i show you how to wire up the 8 speed transmission, as well as the battery tray modification. And we fire it up!!!!! So stay tuned!
If you have any questions about the swap, please leave it in the comments so others can see my answers (This helps others, possibly years later if they have a similar question).
I hope this video shows you guys that it is not to complicated to do a Jeep Wrangler V8 conversion at home by yourself. Its not the cheapest project, however you can slowly buy parts, and do it yourself!
Thanks for watching

[@matthewjohnson5334]

On the 8 speed transmission there is not alut of info and was wondering if u got to change the valve body out iv seen in other videos

[@JKGearandGadgets]

@@matthewjohnson5334 you don’t have to. But if you want the manual shift option (tap shift), then you can send the stock valve body to Jeep speed shop and they will reprogram it

[@willb3018]

I hope everyone appreciates the effort he puts into these descriptions of what you need to do depending on models, etc. Many KZbinrs just tell you what they did with their application. Nothing wrong with that at all. Just acknowledging the extra effort here.

[@JKGearandGadgets]

Thank you 🤘

[@aguywithajeep]

Okay Ben, it’s videos like this that get me in trouble. You convinced me I could do a 1 ton swap in my garage by myself, so I did. And here you are convincing me I can Hemi swap in my garage by myself... so I have to.

[@racinginrushhour5816]

I’ve been building cars for a long time. Bought a 2015 charger motor with the recommended 2010 Jeep steering pump. The intake tube runs right into the steering pump. I’ve installed twin turbos on a 2013 coyote that no shop wanted ti tackle. What steering pump is correct?????

I remember watching this before, during, and after my Hemi swap! I put a 2022 5.7L Hemi and 8 speed in my 2008 Jeep Rubicon and loved the whole process. I also did in a shed, on the floor, with all hand tools. If I can do it, you can too! All it takes time, money, and determination! 😁👍

your vids have inspired me to spend the kids inheritance, lol. I got a rust free 93 YJ to modify at Christmas. Then the wife saw our son's Gladiator Rubicon when we went to Texas for a visit. Needless to say back home to dealership we go. Now the owner of a 21 Mojave, just looking for some desert in the hills of Tenn. Best wishes for you and family.

When I did my LS swap I was the most worried about the wiring and it turned out to be the easiest part of the whole damn thing

[@kevintucker7606]

I hope you didn't lose power for very long. I'm in Houston and we went almost 72 hours, no lights, no heat. Luckily we had water and none of our pipes burst! I got so desperate I was burning scrap wood in my fireplace!

[@StormbornJKU]

You definitely make it look pretty easy putting a hemi in a JK. I feel like it’s way harder than you make it look, but to be fair you make everything look easy haha

[@JKGearandGadgets]

It’s easy! Lol

[@EnfieldJoe]

Very good tech on this swap. I hope that at the end of the project, you summarize the total project cost.

Keep those OG AK plates alive! I think I know why you keep residence up here wink wink lol

[@JKGearandGadgets]

We have been planing doing live videos! Hopefully we will start it up soon. As for comments on old videos, I have a KZbin studio app which lets me look more in depth to my channel and I can view all comments as they are posted, no matter how old the video.

I would be super happy just with the 8 speed swap on my diesel 😉

[@gogerwi]

Sure makes it nice to have that bumper, grill, radiator, condenser out of the way. BTW, 23 people died during the freeze last week while out of power. Several were elderly seniors without power in single digit temps for days.

Like the videos but the temps in Texas were 0degrees in much of the state. The loss of power and cold were kind of a big deal given our power grid. Nevertheless, keep up the work and the swap looks good.

wow never actually been this early before

[@austinlittle924]

I'm a little late to the party but just wanted to say thank you for all the good information you put in the videos. Always been a DIYer so they give me some new ideas. Question for you, I have been debating how to go about this swap and I have a friend that has a dealers license that can get me into auctions for salvaged vehicles. If you had to do this again do you think buying a rolled ram with a Hemi and 8 speed would be more cost beneficial in the long run? and possibly cut down on the number of parts needed?

[@JKGearandGadgets]

Yeah grab a 5.7/8speed from a 4x4 and that’ll help out for sure

[@johnsmith-qz4bv]

great video ....

[@ItsMojoHQGaming]

I have bell notifications on but had to find out this video came out on instagram :( Why does youtube suck.

[@millstonejeepworx]

Great video Ben. Thanks for the update. I'm still prepping my motor. Looking forward to getting to where you are with it. Question, I have a manual trans also. I was under impression that you need the JK auto trans mount. Did the manual work fine? Thanks

[@JKGearandGadgets]

There might be a difference between the 3.8vs 3.6. My 3.8 manual mount worked

[@millstonejeepworx]

My is an '08 manual. So I guess I'll try my existing mount.

[@JKGearandGadgets]

@@millstonejeepworx it’ll work

[@mikeh.8487]

Great stuff Ben! Spent a good amount of time thinking about LS vs Hemi swaps for my 2012 Rubicon, while keeping it manual. Is the Getrag238 the best option for the 6.4L Hemi?

[@JKGearandGadgets]

It’s pretty much your only option. Lots of manual lovers go that route and from what I’ve seen a lot of them regret the decision and wish they went auto.

[@rudy4370]

NEW VIDEO!!!!!!

[@KDUCATI]

How did you route you transmission oil cooler lines? Mine go right over the passenger upper control arm mount and I only have an inch of clearance at ride height.

[@SimonElenor]

On the one I am doing I rotated the fuel rail. Now the fuel fitting is on the passenger side.

[@JKGearandGadgets]

Good idea!

[@JKGearandGadgets]

I would, with the 5.7 you would be ok depending on tire size though. At a minimum, throw some chromoly rear axle shafts in

[@danbouffard8194]

just wanted to no how much you have in total cost on that beast

[@kylenewton4798]

Other than the drive shaft lengths. Would there be any difference from a 2010 jk 2door from your 2010 jk 4door?

Ben I was curious how you were going to modify the stock battery tray, looks like you decided to go Barnes 4wd. Is this because it was a pain to modify the OEM, or does the OEM flat out not work, Thanks.

[@JKGearandGadgets]

All covered in the next video! The OEM will have to be modified to fit with the hemi. Since we are cutting some of the OEM tray, we need to add something better to make sure our battery is secure. Of course another option is buying a full steel that is bolt in for the hemi swaps
