I just looked through ATR's 98,99,00,and 03 catalogs and did not see it. Was it anything special? I have this Stant one and it works fine. Stant Manufacturing
Bud, I lost the cover of my ATR catalog, but by the date since I've had it, it should be the '98 or '99 catalog. Go to page 50. It's a box in kit, not a diagnostic tool. HTH.
