(2020 Ram 1500 Classic Tradesman, Quad Cab 3.6L gas, tip start).
I did not have the harness to the hood latch area.
1. Ordered correct hood latch w/switch: 68159725AB Hood Latch $34.58
2. Ordered wiring kit w/mating connector and wires - this allows you to make up wiring from the hood latch to the plug beneath the PCM but I just used the mating connector and wires and made up my own harness to the underhood ground lug and direct to the BCM C1 connector: 68065018AA Wiring-2 Way $27.85
3. Nothing installed in BCM C1 pin 11 (Hood Sensor for my particular truck); ordered the correct BCM socket(s):

KOSTAL Automotive Connectors
I ordered a few (at $.60 each) and practiced a bit to make sure I had the right crimp tool & technique.
4. Key fobs examined; mine had 3-button overlays (Panic-Unlock-Lock) but have ALL the contact points on the circuit board. Ordered new overlays from Amazon for 4 function to include Remote Start - KAWIHEN Keyless Entry Remote Key Fob Skin Replacement for Chrysler Town AND Country Dodge Durango Grand Caravan Journey Ram 1500 2500 3500 Jeep Grand Cherokee GQ4-53T M3N5WY783X IYZ-C01C

5. Programmed the BCM to let it know the switch was there and tested switch state with AlfaOBD.
6. Enabled the rest of the parameters using AlfaOBD and then reset the RF Hub using my PIN.
Works great!! Total spent in materials for this project about $80; already had the miscellaneous wire, wire loom, ring lug for ground, heatshrink, etc.
Big thanks to Jimmy07 for calling out the correct BCM terminal and 1500ram12 for the Alfa walkthru.
NOTE: If you think you have everything right and attempt to Remote Start...and then your truck locks itself and honks but does not start:
1. Recheck your wiring.
2. Verify your programming.

3. Look (using AlfaOBD) and check the logs and examine Last remote start event; if it says something about Remote Start Inhibited you may have tried to start it before everything was wired and programmed correctly.
Look for a section like this:
Remote Start Enable Data:
Ignition Status: RUN Position
Remote Start Mode: Off Inhibit
Off Inhibit: Yes
RKE Messages Received: No
Any Door Ajar: No
Key in Ignition: Yes
Brake Pressed: No
Hazard Lamps On: No
Remote Start Enabled: No
Remote Start Programmed: Yes
Auto Transmission: No
Hood Switch Programmed: Yes
Start Counter: 0
Failed Counter: 0
Remote Start Inhibit Cause 1:
Inhibit Reason: Not enabled
If everything looks right and the hood switch is working and readable then go back into programming with Alfa and look at Active Diagnostics (this is where you usually select
Car Configuration Change).
Don’t select that...look for
Remote Start Temporary Disable ...you have two choices...Enabled or Disabled.
Oddly enough the parameter name and the choices are inconsistent...Remote Start Temporary Disable, set to Enable, allows it to start.
Go figure... [emoji849][emoji2959]
