    Wanted to update on the shift light install. 2 important things I learned. 1 you cannot fold the coil pack wire and clamp the GMR pickup, it cancels the signal out! I had called MSD and they actually told me to fold it? 2 mine would not work until i grounded the system to the battery not the chassis.

    Tomorrow I will try to write up an article. I drove the car today with the light in a “test” location.
