can any one else help me some one told me that you can take it of one of the 4 wires that run to coil number one i dont want to try this and wreak the tack or anythin

[scherger_16]

followed that wire and it ran to a plug that conected to nothing i took the aftermarket tack and tied it in with ignition coil 1got a signal but it only gave about 1/4 of the signal because its only getting one signal acting as its a one cylender motor rather then 4
