does any body know what wire on the gauge cluster harness is the tach signal wire any help is very appresiated

ya i do but it won't give you a aftermarket tach signal, ust to let you know i assume thats what you want it for right??the slot for the tach in the under hood relay/fuse box won't work either, you have to buy the autometer tach adapet model number 9117 and you have to cut the red wire going to the coil and wire it in, its like 70 bucks or so.
