These are the parts I bought and the prices I paid. Some prices are for new, some use. Everything is OEM! The most recent parts are first in the list. I converted to 134a for the AC system to not have to deal with that insane leftist green refrigerant. All that was required were 2 lines (the fittings are different for 134a. All the other parts are the same; even the oil. Better and cheaper for the system. Sorry for some of the the shorthand. Tired to keep each item to one line in my iPhone. I put notes next to some of the parts for clarification. A lot of these parts were necessary because I was converting the interior to the facelift interior. I would recommend that anyone doing this start with a 2015. It would save a TON of money and time. The small dumb things add up. Many parts also needed to be purchased due to inept removal of the used parts. Cut hoses, broken sensors, smashed/bent brackets/coolers. Make sure whoever you get parts from knows how to undo a spring clamp! That could have saved me $500 alone. Also there are many provisions for different modules/wiring on the 2015 and up that need to be accounted for.

AC hse 134a 68245378AE $89 - Coversion to 134a. Can be done to any LX. Just need the right lines.

Hllct steer rack 68416734AB $600 - This is a big one. If wanting EPS you need this. Hellcat has the Competition steering option. What does that mean? No clue, but the rack is unique to the Hellcat and Redeye. The Scat and SRT have a similar rack and selectable steering feel, but the part number ends in 33AB. Took me eight months to find this rack. Still the only one I have seen available. The Demon and 18WB used an electric rack but it had a different part number. That PN did supersede to the 34AB I believe.

Steering column $175 wanted power tilt column.
Brk tbe bndl 68190129ad $138 - All the front brake lines needed to be replaced. No because they're bigger in diameter for the BR4/BR7 brakes, but because the bends at the ABS modulator are different.

Inner quarter panel trim L&R $178 - The 2013 quarter panel trim is identical, but mine didn't have Harmon sound. Needed the speakers. If I went Alpine could have kept my quarters.
Rear view mirror w/AHB $45 - 15-16 the uConnect microphones are on the mirror. 17 and up place them on the headliner. The mirror harness is then different based on the year you're working with. I didnt want to replace my headliner si I went with the 15-16 mirror. This required some pin and connector housing changes for the mirror and dash harnesses.

Dropping the rear end and fuel tank. A simple floor jack and a block of wood were all that was needed. Perfect balance! The fuel tanks appeared to be identical but there may have been some subtle differences I'm not aware of. The vapor recovery system and hoses are identical though. Installed pressure side pump and return side module. Bought a Chinese tool off eBay to open and close the lock rings. Do not even bother trying to do these lock rings without the special tool. You'll totally f-up the rings.

That's a lot of work. My hat goes off to you. I have a question for a trans upgrade I am doing in the near future. Do you have the schematics or know where I could find the schematics for the 2013 which mine is a RT though but they might still be the same but I am looking for the HDLP DASH connector diagram for the 2016 Hellcat versus the 2013 RT because I am trying to find the pin for the ignition coil power. I think its Pin 2-F343 on the HDLP connector side for the Hellcats but I need to know the diagram for the 2013 Challenger RT and if you know where I can find it on the internet or if you would have it that would be very helpful thanks. You can message me or whatever but I really could use the info.

Engine and trans coming out here. Took 3.5h (front bumper was already off though) with basic hand tools in my driveway. Talk about shadetree mechanics. Very hillbilly for sure. I used a Harley motorcycle jack and some boat blocking to pull the engine forward. View attachment 986872

Hey man, I’m not certain but I think you may have voided your warranty. ?

It is such a beautiful dash. I will be looking out for the 2020 stitched leather dash though.

Sure must be nice to have the witech interface and account to get the modules programmed. But since you are swapping everything is it needed? (ah, I see you bought the components rather than part them out from donor HC)

That big kid sure can make a mess. :p

BTW hope the steering wheel was locked, clocksprings don't like to be over spun.

For simple TIPM/BCM mods I use AutoEnginuity or Alfa OBD. For the programming I used a Controller Technologies Pulsar cable with wiTech Aftermarket.

Setting up the 2018 tank with the hellcat pump and return. All the vapor recovery lines are the same from the 2013. The only difference was the the pressure line (its bigger, but goes in the same location).
987037


Cleaned k-frame ready for the engine:
987038


The HVAC boxes are nearly identical except for the blower motor resistor. Even the harnesses are almost the same. I probably could have swapped the connector on the existing blower motor and used the box, but I got the box for pretty cheap. The first one I received was damaged in transit. The second one was also damaged. Here I am making one out of two. Many moving parts to say the least.

Here is a shot of the fuel/brake/purge lines. All lines, separators and clips have to be ordered individually. The only difference in the brake lines are their connections at the modulator. 95% of the length of the lines are identical. I had assumed that the lines would be a different diameter but no. The purge line was the same but I ordered it because I was making the whole bundle new anyway. The fuel line is much larger. All the separators are different because of the larger fuel line.
987040

Complete rear end going in.

987042



And the main event:

987044


I used a come-along to pull it into the car. All k-frames are the same. I think I even saw that they're the same for all LX cars. Not 100% sure about that one though. At this point I had already put in the Hellcat ABS modulator (I already installed the 2019 HCU on the modulator. There is some difference in the 2019 HCU. Not sure what, but it was cheap enough to not have to find out it wasn'o compatible down the line), crossover brake lines and master cylinder/booster. The original headlamp-dash harness is still installed. If I had had the harness it would have made my life a million times easier to install it before the engine. Washer bottle is the same as is the washer pump. The level sensor is different but is only $3 and is easily replaced.

All slid in:

Gutted interior. Windshield had already been replaced with a 2016 Challenger part that had provisions for humidity sensor and rain sensors as well as the AHB camera. The new style roof airbags are already installed here. Mirror is 2015-2016. In 2017 the uConnect microphones went into the headliner. I didn't want to change out the headliner so I adapted the 2013 mirror harness. The plug at the UGDO/compass module needs to be changed and the pins at the a-pillar connector need to be changed around.

987182


New sound deadener mat installed as well as HVAC box. New mat has stand offs for BCM mounting. Holes and rivnuts still needed to be installed in the kick panel area. Transmission tunnel cover has been replaced. New holes drilled and tapped for airbag module. I used the transmission tunnel sound deadener to determine alignment for the module. It fits very snugly here.
987184


Old harness coming out while routing 2018 body harness. I was able to source all the fir tree zip ties for the harness from the OEM supplier and replaced them so the harness installed perfectly. Not easy to get small quantities from Hellerman Tyton. There were a few new holes that has to be drilled to secure the harness to the body, but 97% were existing. The Body harnesses are pretty much all the same except in 2017 the seat harness wiring was all changed. The wires and connectors are the same but pin locations changed.

Shot of the new mounting location with the bolts for the ORC module. Used the 2013 Hardware and one original mounting hole. Two holes needed to be located, drilled and tapped.

987187

Here is the installation of the rear console bracket. I took careful measurements from a friends Challenger for placement. I used some nice flush rivnuts. There is very little meat for the right one as can be see but enough to make a strong connection.

Here is my solution for mounting the BCM. The 15 and up challengers have three studs to mount the BCM at the kick panel. I used rivnuts and the bolts from the 2013 c-pillar impact sensors. Door harnesses are already installed here too.

987191


Here you can also see the climate control module. Its unique to the 2019. Earlier modules cause the desired temperature display to read totally weird.
987192


Roof airbags essentially mount in the same location but the mounting bolt and u-nut need to be clocked 90 degrees. Here the new hole is drilled. Original hardware was used. To fit the new airbags properly in the headliner the blue foam spacer blocks needed to be removed. This allows the headliner to fit snugly to the airbag.

987193


987194


987195


Installed flush rivnuts and made locating holes for the front end of the airbag at the a-pillar.

Some interior installation. 2018 SCCM is installed for the red lighted airbag. 2013 door panels are not even close to lining up with the dash.

So how does the VIN work for this? Does the PCM and all the other associated modules show a different VIN than what is on the dash?
