Got it!! We looked closer at the book and there was 2 wires coming through the firewall that was green w/ white stripe, well apparently somebody switched wire colors so we run a new wire and got here going. I got it on the HWY to see what she was running at 70mph, 3400rpms, does that sound right? 68mph and under the truck runs smooth, but 70 and over it vibrates to bad, may have something to do with mud tires 8)
