hi...i just got an aftermarket tachometer from summit racing made by summit and its very simple...i got the ground on, the power wire on, and the shift light wire on, but now i have the tach wire that goes to the external dual coil that i have but i dont no which connector to splice into and each connector has a pink and yellow wire......so if anyone has a tpi ignition setup and knows what wire to use that would be helpful. the wiring diagram that they give you is very small and not specific. thank you to anyone that can help.:hail:

 

the wires should be pink/red and white, you tap into the white wire

 

gotta love the handy little search button, i had the same question...
