View Full Version : Tachometer wiring

03-13-2008, 06:57 PM
I just got an original AMC tach from a 68 AMX. Tried hooking it up to my 68 Javelin to see if it worked. According to my wiring diagram you hook it up directly to the coil + and -. Tried that and the car wouldn't even start. Tried every combination of wiring possible and no go. Either the tach doesn't work, or I'm hooking it up wrong. I'm thinking the latter. Anybody know how to hook it up? Thanks. Update- Just went to Eddie Stakes site and found the wiring diagram. Never mind.
