I have converted many trucks to 5.0 before, from 1984 all the way up to 2002, sorted them all out and completed over the years. Now this one is a new set of challenges. The 07 truck has a completely different system where all the body modules are part of one big computer, basically in the the CAN BUS system the PCM, instrument cluster, and body modules (like restraints computer) are all connected and talk to each other.

I have spent months (if not years now) researching how to defeat this with several options on the table. The best option I had was to use the wiring from a earlier truck as a "go between" the 98 5.0 stuff and the 07 can bus stuff. Finally with the 05 Ranger wiring book and the 07 Ranger wiring book on my desk I was able to determine it might just work. Then it happened...........

I saved everything from one of the 05's including the dash, frame, wiring all of it.

[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]The 05 Ranger under hood wiring was checked on paper..... it appeared to match up to the 07 side of things 100% (on the truck side, more on this later) AND the 05 Ranger still had the 42 pin plug C110 that I am very familiar with. So could it be true? Would the 05 ranger under hood harness plug into the 07 dash, fuse box, ABS brake controller, speed control, heater, etc etc........... only one way to find out
