Chrysler NGC4 (MPC5554MZP80 CPU)

Mostly normal brands. Should be identifiable from searching. Just V1124 I don't recognise, but it might be identifiable with some searching.

I didn't find a damn thing for the bigger one. Who on here said something about their association with Chrysler?
Updated previous post. Just that bigger one I don't have a clue about. And the high side driver VN800s vs datasheet VN800PS-E.

Tried AI
Maybe it's my personal preference settings, but ChatGPT seems ... less shit than Google. I'll have to figure out the hard way.
Apparently the "SC" part means custom ASIC.

Got another one. 2009 Dodge Journey.
This one includes a bunch of stuff, including the entire engine.
Transmission blew and owner gave up on it. I have quite a few paid hours into working on this vehicle over the past couple years.

Busy day.
Pulled everything

Cut off bellhousing so I can run it outside the vehicle.

Sorting out wiring. I think I have everything but the pedal wired up as well as I want, including gauges.
Swapped a couple 12 volt supplies from TIPM for one less plug on that bulky thing.
Really looks like park over can, and that's handled by the ignition module. Ignition and ECU use same brake signal, don't know yet if it's required.
After I get it running, I'll test igniton CAN straight to ECU CAN; hope I won't need a new fuse box to test that. Then if gauges will work on the higher speed ECU CAN bus... If not, tablet and OBD dongle.

These ecus are a annoying as to work with i have a customers old dodge truck with 1 in out of a 300c. It has all the other modules under the dash abs etc just so it runs even with security turned off to not need a key had to send the ecu away to be unlocked and the security bypassed

I meant to test some of this before I ripped it all apart. When owner made up his mind, I excitedly got going tearing it apart.
On some, there's no VSS sensor on the transmission, so you need ABS for CAN bus wheel speed... unless you add a VSS sensor and get the right ECU programming. Had that problem on a 300 before, dumb shit, wouldn't get out of first gear. The customer's choices were, either find wiring diagrams so I can run a new wire, pay me to gut the interior to trace the wires, or sell it. He sold it, it started getting a misfire too. Was a money pit. Hemi too. Just did all calipers, rotors, plugs, and coils before that.
If I new about https://connectorrepairkit.mopar.com/ I could have just run the wires. Pretty sure it was old enough to look up for free.

Pause as soon as it starts (13:41) and look at the options.

Nope, chopped this one off completely... damn it.
