I just recently replaced the coils and the deck for the coils on my camaro. My tach isnt registering anymore, it worked fine before. Any thoughts?
1994 Chevy Camaro Ignition Coil & Module V6 3.4L

my 93 book shows tac signal is the white wire coming out of the icm module. check it to make sure its not damaged both wire, plug in and plug. on second look there are two white wires, its the one closest to the blue and black wire. should be from one end to the other, pink, black, purple, yellow, tan/black, white, white, blank, blue/black, red/black
