Rated 5 out of 5 by from Easy to install I purchased this to get the Chrono Tach working in my 1981 Ford Mustang 03 Cobra swap (4.6L Supercharged) project. The instructions was super easy to follow, install was very simple and I was able to hide it in my glove box for a simple easy installation. A++++ for another fantastic Autometer product.

can it be use to make work a oem colt 93 tach ( witch have distributor ) with a 4g63t swap (witch work with coil pack)

Asked by: evo393
Hello, thank you for your question. Unfortunately not knowing exactly what the signal requirement is for the '93 Colt tachometer, it's difficult to say for sure. We would require some additional details on the 4g63t as well just to determine general AutoMeter tachometer compatibility. We’d recommend reaching out to them by email with as many details as you can:
