Howdy guys, new here. I have a 1999 Dakota 3.9 automatic 2wd that was my daily but it was very rusty. I bought a 2002 dakota in good condition with a 3.9 automatic but it had a blown motor. I put the motor from my 1999 into the 2002 and most of the harness stuff is the same except for the plug that goes into the fuse box on the one harness. On the other harness the injector plugs and some other plugs are different. Any input on what to do?

 

User your original harness to the truck you are putting the motor in, and swap the injectors over, along with any other sensors that don't match up.

 

The injector change is EV1 and EV6 (I warned you of this in your other thread). Use the 2002 truck harness and change out the injectors and hope they are good, or get EV1/EV6 adapters to suit the condition.
