That should do. Planning to try tomorrow evening.
Shouldn't have more than transmission and lost communication DTCs, and O2 sensors, because no exhaust.
Seems there's 5 volt supply to engine from trans connector too... glad I kept that.

Sorting out wiring. I think I have everything but the pedal wired up as well as I want,

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

Anybody have some where/way I can double check this one?
This part bugs me

I couldn't find a wire that made sense for where it would have originally went. These pinouts already had some errors, this might be another error.

Wouldn't command the starter.
Didn't have PRNDL, Sorted that out.

(Closed meaning connected to ground... they didn't specify.)
Still won't command starter. I'll have to wire up an OBD port and put the scanner on it.

Apparently the brown/orange is an output from the engine harness, to pedal.

Found the answer
Code B2101
https://www.chryslerminivan.net/threads ... lt.180326/
Run/start pin on WIN module is an output to a specific pin on TIPM, pin 30, right next to the 3 CAN bus connections on TIPM C7. Of course, that's a wire I snipped flush, thinking it was a low current output FROM TIPM to something else; so I have to pull the connector apart to fix that. Just held the wire in place for a quick test. Cranks now.
Now I need to see about these other circuit high codes.
Pinout says black connector, it's red.

Has MAP sensor code, but it runs.

That's pretty wild to see it bouncing around on the strap like that.

[AngelMarc]

I expected it to be louder too. Was a crazy quiet vehicle.

[AngelMarc]

So apparently these ECUs report "circuit high" codes for anything that's simply unplugged, instead of properly informing the tech/owner about an open/unplugged circuit.
MAP sensor latch is broke, so it just wasn't plugged in.

And apparently, if you have a giant intake leak where it struggles to bring idle down, it'll deactivate an entire bank of injectors/coils. I cut the bastard EGR tube and that fell off, 1.5 inch hole.
