does anyone know how to hook up a buick motorsports tach. i have a 5 inch tach with a key operated recall. and i dont know where all the wires hook up. also anyone know where i can buy a key that fits it . thanks
I dont know if this will help you but I have the same tach and the brand name on my key blank is C&K and the key code is A126. I couldn't see any other information on the lock cylinder. I have never seen this type of tach recall system in the Autometer catalogs so it may be something that Autometer built for Buick Motorsports(now GM High Performance).
i dont know why it resets with a key. if you turn the key one way it shows rpm memory. if you turn it the outher it erases the memory.this key can be mounted 2 feet from the tach.but it works just like a tach with a recal switch in the face.
