I am installing an MSD BTM on my 93 firebird and the wiring diagram does not match my LT1 very well. Have any of you installed one? The tech guy at MSD sent me a diagram but it's the exact same one i have. It says that the grey connector( one wire) goes to the tach. On mine one wire on the black connector goes to the tach. Well hell hope someone out there knows how to install one....
