Can any of you guys tell me the wiring for this tach. It has 4 terminals in back that say T B G and L There was a red wire on B and a yellow on T the other 2 where bare . The tach came with a 67 SS Conv that i bought and was just thrown in a box with some other parts. Would the yellow T go to the dist. The red B to the power The one that says L would be the Light, and G be ground. Also would this Tach need a power box like some of the Sun tach do. It has a slide in the back that says zero corrector and a srcew that says 4 6 8 These are no problem just need the wiring. I'm running a 427 with HEI Dist. Thanks for any help Dirks SS

T goes to the "tach" terminal on the dist cap
B goes to an "IGN" terminal on the fuse box.
G goes to a good ground under the dash
L goes to a terminal in the fusebox that comes on with the dash lights- or be lazy and tie it in with the one that goes to the "IGN" terminal, but the light will always be on when the ignition switch is on.
