Tach Stopped

85 Bronco 351 W H.o. Auto Dual Exhaust (true Duals) Long Tube Headers With Two Cats And Two In Two Out Magnaflow Muffler. In The Process Of Installing My Dual Exhaust, Which Btw Was A Total Pain In The ****, My Tachometer Stopped Working, There Are Two Wires Leading To The Coil And Both Are Tight, Any Hints On Where To Start Looking For The Cause? Yes, It May Just Be That The Tach Is Dead, But I Figured It Does Not Hurt To Ask, Thanks

First, I woudl check all of your fuses. Then (I know you don't want to hear this) start tracing wires to see if anything got cut, burned or pulled loose.

Follow the tach test wire off the coil.

There should be a couple of more connectors on the left fender panel where the tach wire "Y's" off. One goes to the ignition module, or computer, etc... the other goes to the tach in the dash etc..

Should be a green/yellow stripe color wire you are looking for.
