I have a 1999 Ram 3500 base truck with a Cummins/5 speed. I also have an interior out of a 2000 Sport model that is power seats/heated/lumbar, power windows and locks, overhead computer console, and it has the wiring for inside the cab, and "most" of the under the hood wiring, including the power distribution box. A few weeks ago, I removed the interior, and installed the wiring for inside the cab, the seats, headliner, and overhead console from the 2000. It ran good, but I had no high beam headlights or cab lights, no speedometer or odometer. After a few days of not finding the issue, I changed it back to the 1999 harnesses, as this is my daily driver. Now I have a crank but no start. It starts for 3 seconds and then stops. It does this 3 times and doesn't start again. I hot wired the vp44, so it's not that. Nothing else changed. I have FSM downloaded for each year of wiring, and I'm usually pretty good at wiring, but this is kicking my butt. I do see some changes between the 2 years in the schematics.
Yesterday, I hooked the 2000 wiring back up, and it starts immediately....ONCE I HIT THE DOOR UNLOCK of the key fob, but still have the light issue and no od or speedo. This sounds like a anti theft activation (VTSS?). Is the anti theft stored in the PCM? I tried locking and unlocking the doors several time, and changed back to the original wiring, but it's still starting for 3 seconds x3 and stopping. I'm really not sure where to go from here. Suggestions??
