2000 dodge dakota door locks

There will be a power feed to both door switches. The BCM is indeed separate from the door and is tucked behind the dash. The wiring you tapped into on the driver side leads to the passenger switch which progresses to the BCM which has direct connection and control of the lock motors. As to whether the BCM is ok, most likely it is. It's hard to mess it up doing this kind of stuff.

You seem to really know these trucks.. You don't know which wires should be showing what voltage do you?

Each of the wires you tapped should show +12v when you hit the switch in the corresponding direction. +12v on the OR/VT during lock, +12v on the PK/VT during unlock. Red at the switch should be constant hot.

Just wanted to give an update and say thanks! The harness plug connected to the master switch much of fell out.. When I pulled the passenger side master switch out it wasn't connected. Door locks and Window now works! Only other issue I had was with a CEL where the ECM and TCM were not communicating. Did some research and it was due to a small gauge GREEN/ Red 3rd ignition wire that needed to be wired in. I guess that wire ran to the transmission. I used the Aux harness 2nd ignition output wire to power the 3rd ignition quenching relay. The 2nd ignition used the flex relay so I don't see there being an issue using the "2nd ignition pink/white" wire. I used 2 diodes to protect the remote start wire and one for 85 to 86. All is working great now! Even the horn. Thank you so much!

Good Job, congrats on a job well done. Yes! Everyone loves the horn, can't get enough horn.
