This is the kind of thing that gives mechanics nightmares. I wouldn't touch your truck with a ten-foot pole. Your 98 engine requires a different ECM and wiring harness than your 93 truck. I shudder to think of the head-banging frustration of trying to cobble the two together. Far better to just trade up to the truck you want.

Just my thoughts on this: You are opening "Pandora's Box" and will probably have endless headaches from this. Think hard about the task. Wish you luck, ---- No hard feelings, let us know what you do and how you made out, best,
