i've swapped in a '96 5.7 vortec and 4l60e into my '86 k5. it works really good. i just cant figure out which wires need to be spliced to get the lockup torque converter functioning. i've been looking at the wiring diagrams for a few hours and haven't been able to come up with a solution. i could sure use some help from someone that knows which wires i need to splice. thanks-brian
