Default Best 4l80 swap harness??
Hey yall, Ive done some searching and cant really find a solid answer, maybe someone here can help.

Are any of the conversion harness' different/better than the others? They range from $150 to $275 and one doesnt seem to be any "better" than the others?

Have any of you experienced problems or success with any one in particular?? THANKS

The Nelson one is only like $90, but that's for a NBS truck. Not sure what you have

Just changed a few pins on mine and ran a wire to the PCM for extra speed sensor.
