I dont need any of this as I'm doing the 3.4 swap myself but I'm actually working on that part tomorrow.
From what I have read, you just need from the 3.0 harness the 2 plugs the connect to the dash harness.
Read the 2 diagrams and match all wires, I would steer clear of splicing to avoid problems later. Solder or better yet pull each pin 1 at a time. As soon as my headers gets here I will be ready to slap it all together.
Where abouts are you?
I live in Victorville Ca. My wiring harness has been cut into about 10 different pieces. That is why I gotta splice it back together.
