How to splice 2 injectors for the 3.9 to 5.9 swap
I have the 5.9 engine and i’m currently rebuilding it, but in the meantime i need to know how to splice the 2 injectors on the 3.9 wiring harness. I’ve looked everywhere, but couldn’t find a detailed description of it. If anyone can either give me a detailed description on how to do it or maybe a link that you know of that will show how to do it then it would be much appreciated, thanks

Need a wiring diagram. Factory service manual is your best bet. (I don't know if the Dakota manuals are available in the FAQ/DIY section here... worth a look.) But, injectors get power from a common source, there is a splice in the harness (or two) where the individual wires break out. Injectors are controlled individually though, and you need to wire the ground side of the injector to the correct pin on the pcm connector.

I was off by a page. I thought it was page 20, it was 19.

If you have a 4x4, then the 2wd harness will not work. The engine harness includes the driveline portion. Also, the ram, ramvan, dakota, and durango engine harnesses are different. They are also different by year grouping (97/98, 99, 00, 01/02, 03/04) and by engine (3.7, 3.9, 4.7, 5.2/5.9). So the overall odds of getting the exact harness for your exact year, body, (desired) engine and driveline is pretty thin. It's easier to just pull the connector apart and stab the 2 extra wires in.
