Well today I received an AutoMeter and AutoGauge Tach. THEY BOTH WORKED!... In the previous posts in the Electrical Systems Forum I explained how it was done along with some pics.. The total cost for a tach installation

Tach $79.00
Term. Sleeves.... $1.49
Wiring and shrinkage tubing...... $3.00


Take your time and be careful..

P.S. The AutoMeter tachs need an AC signal and I have the specs. no need to add any other electronic like I first thought..
