I replaced the neutral safety switch and pigtails. Tried 2 different dashes, but the "D" on the dash doesn't get the square around it like the other gear indicators do when in the gear. The transmission goes into drive and it drives fine, just doesn't show that you're in Drive on the dash. Does the neutral safety switch just tell the TCM what gear you're in, and the TCM tells the dash? Or do the wires split, like a separate wire for each?
