Ok I've figured out what wire does what on the 3 pin, I think. Now I can't find anything on the 5 pin wire colors, colors are dark brown/yellow, green/gray?, Brown/black, yellow/pink or red, dark brown/green???? I don't care if the the shifter works on the dash I just need all gears to work with overdrive

Have a look here, see if you can find what ya need.

 

Don't spline any wires. Make sure you have the correct transmission for your truck.
