Forgot to mention the starter. I had to use the 4.7 starter, there is not enough room on the passenger side to mount the starter. I tried a couple of different starters (Jeep 5.7) but none would clear. Learned this the hard way after the engine/tranny were mounted so I drilled a hole in the 5.7 flexplate and mounted the 4.7 starter. If you use the 4.7 flexplate you will be OK. Also the engine sits to passenger side a few inches closer to the control arm vs the driver side. Kinda weird to me that it was not centered in the frame.

AC Lines. I had to use the both the Ram and Dakota AC lines. You will see the Ram AC lines at the compressor and the Dakota's lines at the filter dryer and at the condenser. I took my hoses to my local Napa dealer to get them fitted. I also had to get a low side port ($4 from ebay)welded onto the suction line near the filter. I used a Jeep Liberty filter dryer because it has the extra port for an AC switch. I have a 3.7 Liberty and I noticed this port I also noticed that the suction line on the Liberty looks like it work if you needed the AC line ends. I don't think it is long enough but an AC shop can replace the rubber hose. BTW I was at the local pullapart and I noticed a 2000 Dakota had the same filter dryer setup.

Can't wait to hear about the cruise control. I'm hoping you get that figured out without having to replace the steering wheel. 🤞

Brake switch Circuit 2 info, I found this while working on the cruise control circuit. BS2 circuit is a ground signal on the Dakota ECM but is a +12v signal on the Ram ECM. My truck had some drive ability issues that I could not figure out. anyway after I put 12v on this circuit it runs much better. Without the 12 the ECM was thinking that the brake pedal was push down.

Learned a few things this weekend about ABS on these trucks, on 2 Dakota the ABS light on the dash was flashing and on one of them the light was flashing and it was chiming too. The Chrysler DRB3 would not access the ABS module but a Snap On Modis Edge Scanner will. All we had to do was set the tire size in the ABS module. The Tire revolutions per mile on both ABS modules was set a 400 not the 695 for the 16" OEM tires.
Both trucks are 2002 with 5.7 swaps.

Leak Detection Pump CEL P0499 NVLD Canister Vent Valve Solenoid Circuit High

I learned something else today, I had one CEL since my Hemi swap was complete, well today I finally fixed it. All I had to to was cut the white/blue wire on the Leak Detection Pump pin 2 and connect it to ground. On the Ram this circuit connects to ground but on the Dakota it routes to the Starting/Charging system. The Leak Detection Pump is located under the fuse tray near the battery. You can lift the fuse tray up after you remove 1 10mm bolt and push on 2 tabs on the fuse tray, it will lift up a few inches giving you access to the plug to the pump.

DBW gas pedal:
View attachment 109800 Here is a picture of the DBW Durango pedal. The pedal mounts to a flat piece of plastic, wish I had drilled a hole and mounted a bolt at the top of the flat piece before I installed the engine. I have it mounted to 2 of the original pedals mounts. The washers are to move the bottom away from the firewall so the pedal is not into the carpet. I used the hole that the throttle ran through to route 6 wires. The DBW pedal has 6 wires that control 2 sensors in the pedal assembly. If either of these 2 sensors are not working the throttle blade will not move. My truck would start fine and idle all day but the throttle blade would not move when I pushed on the pedal I chased this problem for a long time until I hooked up a Snap On Scanner and discovered that the APPS2 sensor was not reading. I changed the DBW pedal and it went to working.
The 03-04 Rams have a throttle cable that runs from the pedal to the APPS sensor, it is located under the battery on the Ram. If you wanted to stay with the Dakota pedal and throttle you can use the older APPS setup. But the cost of the older sensor is about $200 for a new one. The DBW pedals are cheaper and they were installed in everything from 05+ Rams, Durango, Jeep GC...
Where do the 6 wires for the pedal run too? I’m currently doing this swap on a 05 Dakota.
